The option (2) As x → ∞, y → ∞, and option (6) As x → –∞, y → –∞ are correct if the function f(x) = (x - 2)(x + 2)/(x + 1).
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function shown in the picture.
f(x) = (x - 2)(x + 2)/(x + 1)
The above function is a fractional function:
The denominator of the function cannot be zero:
x + 1 ≠ 0
x ≠ -1
From the graph of a function:
If x → ∞, y → ∞
If x → –∞, y → –∞
Thus, the option (2) As x → ∞, y → ∞, and option (6) As x → –∞, y → –∞ are correct if the function f(x) = (x - 2)(x + 2)/(x + 1).

please help Dave drives to work. While driving the car over nine days, he observes his daily average speed and lists it in the table below. Day Average Speed (MPH) 1 45 2 62 3 44 4 70 5 59 6 66 7 54 8 63 9 67 The median speed at which Dave drove to work was __________. 63 miles per hour 59 miles per hour 62 miles per hour 58.89 miles per hour
The median speed at which Dave drove to work was 62 miles per hour.
To find the median speed at which Dave drove to work, we need to arrange the average speeds in ascending order and determine the middle value.
Sorting the average speeds in ascending order:
44, 45, 54, 59, 62, 63, 66, 67, 70
Since we have nine values, the median will be the middle value when the data is arranged in ascending order. In this case, the fifth value, which is 62, represents the median speed at which Dave drove to work.
Dave drove to work at a median speed of 62 miles per hour as a result.

think of a number path start at 8 add 2 to make 10
Answer:
- Each sum which is larger than 10 can be found by first making a 10. For example, to find 8 + 5, we can write. \begin{align} 8+5 &= 8 + (2+3) \\ &= (8+2) + 3 \\ &= 10 + 3 \\ &= 13

Jimmy's dog weighed 60 pounds 4 months ago. Since then his weight has increased by 6% How much does Jimmy's dog weigh now
Answer: 3.6
Step-by-step explanation:
Answer:
63.6 pounds
Step-by-step explanation:
Jimmy's dog's weight was 60 pounds 4 months ago and now it is weighing 6% heavier.
So 6% of 60 is
[tex]\frac{x}{60} *100=6[/tex]
x=360/100
x=3.6
So Jimmy's dog weighs 60+3.6=63.6 pounds

B. x = 0.80
C. x = 1.61
D. x = 1.39
9514 1404 393
Answer:
B. x = 0.80

We suspect you want the solution to the exponential equation ...
4e^(2x) +16 = 36
e^(2x) +4 = 9 . . . . . . . . . . . divide by 4 (because we can)
e^(2x) = 5 . . . . . . . . . . . . . . subtract 4

Sol Levin sold 22 pairs of shoes each day.
Monday through Wednesday, 28 pairs on Thursday,
and 31 on Friday. How many shoes must he sell on
Saturday to average 29 pairs sold for the 6 days
he worked during the week?
Answer:
Sol Levin needs to sell 49 pairs shoes on Saturday.
Step-by-step explanation:
29 x 6 = 174
(22 x 3) + 28 + 31 + x = 174
66 + 28 + 31 + x = 174
94 + 31 + x = 174
125 + x = 174
(125 - 125) + x = (174 - 125)
x = 49

Here is a circle, centre O, and the tangent to the circle at the point (-3, 4) on the circle. У P (-3, 4) X -5 O Oา Find an equation of the tangent at the point P. Give your answer in the form y = ax + b where a and b are both fractions with denominator 4.
Answer:
[tex]y=\frac{3}{4}x+\frac{25}{4}[/tex]
Step-by-step explanation:
when a line is tangent to a circle, it is perpendicular to the line from the center of the circle to the intersection of the line and the circle. so first we are going to find the slope of the line in the circle.
to find the slope use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\frac{4-0}{-3-0}=\frac{4}{-3}=-\frac{4}{3}[/tex] so the slope is -4/3
the slope of the line perpendicular to this is the opposite reciprocal: 3/4 so now we have y= 3/4 x +b, to find b plug in the point (-3,4) to get 4=-9/4 +b, b=25/4 the equation is y=3/4 x +25/4

Answer:
2 apples: 5 bananas: 8 oranges
Final answer: 1 apple: 2,5 bananas ( divide by 2 )
Answer:
D.0.8
Step-by-step explanation:
The ratio in mathematics indicates how many times one number contain another. To find this ratio you must make a division of both. numbers. For example the ratio X to Y is X/Y.
As there are 4 apples to 5 bananas, the ratio of apples to bananas is:

Answer all questions olve the following logarithmic ec 2 log10 x + log103 = log10 75
[tex]2 log_{10}x + log_{10}(3) = log_{10}(75) [/tex]
Step-by-step explanation:
We can rewrite the left-hand side as
[tex]2\log{x} + \log{3} = \log{3x^2}[/tex]
Here, we used the following properties of logarithms:
[tex]\log{x^a} = a\log{x}[/tex]
[tex]\log{ab} = \log{a} + \log{b}[/tex]
We can then write
[tex] \log{3x^2} = \log{75} \Rightarrow 3x^2 = 75[/tex]
