If f(x) = 2x + 5 and g(x) = 4x – 1, find: a)  gf(1)              b)  fg(x)            c)  g -1(7)

Let f(x) = 6x – 4x² – 7x³ and g(x) = 9x² – 5x . Find (f + g)(x) and (f – g)(x). Then evaluate f +g and f – g for X= -1. - (f +g)(x)= D; (f +g)(-1) = D (f - 9)(x)= D; (f – 9)(-1) = D

For f(x) = 7x -8 and g(x) =(x+ 8), find (fo g)(x) and (g o f)(x). Then determine whether (f o g)(x) = (g o f)(x). What is (fo g)(x)? (fo g)(x) = What is (g o f)(x)? (g o f)(x) =O Does (f o g)(x) = (g o f)(x)? No Yes

Convert this equation to standard form: f(x) = (x+3)² + 1 Of(x) = x² + 6x + 10 2 Of(x) = x² - 6x + 10 Of(x)=x² - 6x +8 Of(x)=x² - 6x - 8 2
