Question

Find the inverse of the function y=3x-8
a y=8-3x
b y=3/x+8/3
c y=1/3x-8
d y=x+8/3

Answer 1

if it exists, graphically it is the given equation reflected over the line Y=X, if possible.

in that , you can change the Y and the X around, then solve for the Y again, and that will be an inverse, if it is there

Answer 2

i did that but the answer i got wasnt right

Answer 3

x = 3y - 8

[x+8]/3 = y

D would be the one, if it had brackets grouping the numerator

Answer 4

thank you for explaining and helping me :)
