Step-by-step explanation:
Set the equation
swap y and x
So the inverse is
The domain is [4, infinity)
The range is [0,infinity)
The domain of the inverse is [0, infinity)
The range is [4, infinity)
Answer: $1.20
Step-by-step explanation:
To calculate sales tax, multiply the price by the tax percentage.
$30 x 0.04 (4% sales tax) = $1.20
Answer:
1/2
Step-by-step explanation:
Here you utilize the formula of slope which is m = y2-y1/x2 -x1
(-1,5) (1,6)
(x1, y1) ( x2, y2)
m = ( 6-5)/ (1-(-1))
= 1/(1+1)
= 1/2
Answer:
Bottom left
Step-by-step explanation:
The limit as x approaches infinity is 3, so there is a horizontal asymptote at 3. So eliminate top left and bottom right.
Also, the fraction 2/(x-1) is undefined when x=1 (since the denominator is 0), so there is a vertical asymptote at x=1. Eliminate top right
So, your answer is the bottom left graph.
1: 1/2
2: about 1 1/2 hours
