I need the answer to this please!

Question

What is the effect on the graph of the function f(x) = 2x when f(x) is replaced with f(2/3x)?

Answer 1

Both are straight lines with the standard form y = mx + b

So, here if you plug 2/3(x) wherever you see x, you get f(2/3x) = 2 (2/3x) = 4/3x where 4/3 is the slope.

The slope of the line will decrease from 2 to 4/3
