Question

If f(x)=4x²−11x f ( x ) = 4 x 2 - 11 x , what is the value of f(5) f ( 5 ) ?

a. – 15
b. 2
c. 45
d. 280

Answer 1

The value of f(5) for the given function f(x) = 4x² - 11x is calculated by substituting x with 5, resulting in 45.

Step-by-step explanation:

To find the value of f(5) for the function f(x) = 4x² - 11x, we simply substitute x with 5 and calculate the resulting expression:

f(5) = 4(5)² - 11(5)

= 4(25) - 55

= 100 - 55

= 45

The value of f(5) is 45, which corresponds to option c.

Answer 2

Answer: 45

Work Shown

`f(\text{x}) = 4\text{x}^2 - 11\text{x}\\\\f(5) = 4(5)^2 - 11(5)\\\\f(5) = 4(25) - 11(5)\\\\f(5) = 100 - 55\\\\f(5) = 45\\\\`
