The functions f and g are defined as follows
f(x)=-2x^2-3 g(x)=3x+2
find f(2) and g (-4)
Simplify your answers as much as possible.
f(2)
g(-4)
To find f(2), we substitute x=2 into the function f(x)=-2x^2-3:
f(2) = -2(2)^2 - 3
= -2(4) - 3
= -8 - 3
= -11
To find g(-4), we substitute x=-4 into the function g(x)=3x+2:
g(-4) = 3(-4) + 2
= -12 + 2
= -10
