Question

Given the following functions f(x) and g(x), solve (f ⋅ g)(2) and select the correct answer below: (1 point)

Answer 1

For this case we have the following functions:
 f (x) = 2x2 - 10
 g (x) = x + 9
 Evaluating both functions for x = 2 we have:
 f (2) = 2 (2) ^ 2 - 10 = 8 - 10 = -2
 g (2) = (2) + 9 = 2 + 9 = 11
 Then, multiplying both functions we have:
 (f ⋅ g) (2) = (-2) (11)
 (f ⋅ g) (2) = -22
 Answer:
 the correct answer below is:
 -22
