If f(x):=x+4 and g(x):= 4x-1, find a function g such that g x f=h

Expert Answers

An illustration of the letter 'A' in a speech bubbles

f(x) = (x+4)

g(x) = (4x-1)

h(x) = g(x) x f(x)

        = (x+4)*(4x-1)

 Open brackets:

==> h(x) = 4x^2 - x + 16x - 4

               = 4x^2 + 15x - 4

Then ,

h(x) = 4x^2 + 15x - 4
