Question

What is the inverse of y = 3x + 9?

Answer 1

-1/3x+9

Answer 2

you guys mean y=9x+3 right?

Answer 3

A. y= 1/3x-3
B. y=9x+3
C. y=1/3x+9
D. y=-1/3x-3

Answer 4

still got y=3x+9 I think the actual answer is B

Answer 5

cause were working with "inverse"

Answer 6

Hi friend, you just replace x by y and y by x to get the inverse function. and then solve for y . to your problem, when replace you have x= 3y + 9 ---> 3y =x-9---> y = (x -9)/3 or y = 1/3x -3 . that is inverse function of your function
hope this help

Answer 7

so @Hoa our answer would be y=1/3x-3

Answer 8

absolutely right. and that is the easiest way to get the inverse function

Answer 9

thanks!
