Question

The functions f and g are defined as follows:f(x)=2x^2-3xg(x)=-5x-1Find f(-3) and g(7)Simplify your answers as much as possible

Answer 1

f(x) = 2x^2 - 3x

f(-3) = 2(-3)^2 - 3(-3)

f(-3) = 2(9) + 9

f(-3) = 18 + 9

f(-3) = 27 This is the first solution

g(x) = -5x - 1

g(7) = -5(7) - 1

g(7) = -35 - 1

g(7) = -36 This is the second solution
