Question

F(x)=4x² −11x , what is the value of f(5)
a. – 15
b. 2
c. 45
d. 280

Answer 1

The value of f(5) for the function f(x)=4x² −11x is calculated by replacing x with 5. The result is 45, which corresponds to option c.

Step-by-step explanation:

To find the value of f(5), we need to substitute 5 into the expression for F(x) and simplify.

So, we have:

F(5) = 4(5)^2 - 11(5)

Simplifying this further:

F(5) = 4(25) - 55 = 100 - 55 = 45

Therefore, the value of f(5) is 45, so the correct answer is c. 45.
