Question

If f(x)=3x+1 and g(x)=2x−3, what is the product of f(4) and g(−1)?

a) -5
b) -12
c) 3
d) 7

Answer 1

The product of f(4) and g(-1) is -65.

Step-by-step explanation:

To find the product of f(4) and g(-1), we first need to evaluate the functions f(x) and g(x) at the given values. Substitute x=4 into f(x) and x=-1 into g(x) to get f(4) = 3(4) + 1 = 13 and g(-1) = 2(-1) - 3 = -5. The product of f(4) and g(-1) is 13 * (-5) = -65. Therefore, the correct answer is a) -5.
