Find the inverse of the following function.

A. 5-1() = + 12
B. 5-1) = 12 – 13
C. 5-1(x) = 23 – 12
D. 5-1() = x – 12

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
