math

the functions f and g are defined as follows

f(x)=5x-1 and g(x)=-4x^2-3

f(-6)=

g(5)=

simplify your answer as much as possible
i have the first answer which is -31
for the next part i keep coming up with 97 which is wrong

  1. F(x) = 5x-1
    F(-6) = 5*(-6) - 1 = -31.

    g(x) = -4x^2 - 3
    g(5)=-4*5^2 - 3 = -100 - 3=-100 + (-3) =
    -103.
