Question

If f(x) = 2x – 5 and g(x) = 5x – 2, what is f · g?

A.
f(x) · g(x) = 10x2 – 29x + 10

B.
f(x) · g(x) = 10x + 10

C.
f(x) · g(x)= 7x – 7

D.
f(x) · g(x) = 10x*2 + 29x – 10

Answer 1

Answer:

The answer is option A.

Step-by-step explanation:

f(x) = 2x – 5

g(x) = 5x – 2

f(x). g(x) = (2x - 5) ( 5x - 2)

= 10x² - 4x - 25x +10

= 10x² - 29x + 10

Hope this helps
