Question

F(x) = 3(x - 5)(x + 2), then f(5) = and f(-2) =

Answer 1

f(5) = 0

f(-2) = 0

Step-by-step explanation:

Given the function f(x) = 3(x - 5)(x + 2),

f(5) can be gotten by simply substituting x = 5 into the function as shown;

f(5) = 3(5-5)(5-2)

f(5) = 3(0)(3)

f(5) = 0

For f(-2)

f(-2) = 3(-2-5)(-2+2)

f(-2) = 3(-7)(0)

f(-2) = 0

Hence f(-2) is also zero
