If , what is f^-1(x)?
f–1(x) = 9x + 18

f–1(x) = 9x + 2

we have

Let

To find the inverse

Exchanges the variables x for y and y for x

Isolate the variable y

Multiply by both sides

Adds both sides

Let

-------> the inverse function

therefore

the answer is

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
