5. If f(x) = -x2 - 7x +4 and g(x) = -5x - 3, what is the value of f(-2)-g(6)

Answer:

  47

Step-by-step explanation:

Evaluate the functions and find the required difference.

  f(-2) = -(-2)^2 -7(-2) +4 = -4 +14 +4 = 14

  g(6) = -5(6) -3 = -33

Then the difference is ...

  f(-2) -g(6) = 14 -(-33) = 14 +33 = 47
