Answer:
Explanation:
You want f(3) and g(-6) when f(x) = -4x² -3 and g(x) = 5x +2.
Function evaluation
To find the value of the function for a particular value of the variable, put that value in place of the variable and do the arithmetic.
f(3) = -4(3²) -3 = -4(9) -3 = -36 -3
f(3) = -39
g(-6) = 5(-6) +2 = -30 +2
g(-6) = -28
