Question

Would it be 6x-3 or 6x^2-3? Composite function

Answer 1

g(x) = 3x

g(x) = 3( x )

g( f(x) ) = 3( f(x) ) ... replace every x with f(x)

g( f(x) ) = 3( 2x-1 ) .... plug in f(x) = 2x-1

g( f(x) ) = 3( 2x) + 3( -1 ) ... distribute

g( f(x) ) = 6x - 3

You are correct in saying D is the answer
