Question

The functions f and g are defined as follows. f(x)=4x^(2)-x,g(x)=-3x-3 Find f(-3) and g(2). Simplify your answers as much as possible.

Answer 1

g(2) = -9.

Explanation:

To find f(-3), we substitute -3 into the function f(x) = 4x^2 - x:f(-3) = 4(-3)^2 - (-3)

= 4(9) + 3

= 36 + 3

= 39Therefore, f(-3) = 39.To find g(2), we substitute 2 into the function g(x) = -3x - 3:g(2) = -3(2) - 3

= -6 - 3

= -9Therefore, g(2) = -9.
