answer: -3
step-by-step:
okay so first you gotta plug g(x) into f(x) by replacing all the x’s with x-5
4(x-5)+1
then you distribute the 4 by multiplying it by x and -5
4x-20+1
then you add together like terms (-20 and 1)
4x-19
then you plug in 4 for x
4(4)-19
4*4 is sixteen so
16-19
then you subtract 19 and get -3
