f(-) = 9x + 7
OA +1(x) = for
B. 5+1(t) = -92-7
C. 51n) = 7+ 9
D. (n) = -

Answer 1

x-7/9

Explanation:

Answer 2

The inverse function is (x-7)/9

Explanation:

y = 9x+7

Exchange the x and y

x = 9y+7

solve for y

Subtract 7 from each side

x-7 = 9y+7-7

x-7 = 9y

Divide each side by 9

(x-7)/9 = 9y/9

(x-7)/9 = y

The inverse function is (x-7)/9
