Question

If f(x) = x - 2, for what value of x does f (3x) = f(x+1)?

Answer 1

Okay, so what would f(3x) be?

Answer 2

you have to solve for it :P u substitute x-2 in for the Y value in the second equation

Answer 3

then solve for x

Answer 4

Hint:
f(3x) = 3x - 2
and
f(x + 1) = x + 1 - 2

Answer 5

You will have f(3x) = f(x + 1) = 3x - 2 = x + 1 - 2
Am I right?

Answer 6

Can you solve the following equation then?\[\rm \large3x - 2 = x + 1 - 2 \]

Answer 7

:o hmmmm why is she asking answer... just tell her the concept :P
