Question

Given f(x) = x^3 + x^2 - x , what is f(4)?A. 16B. 76C. 256D. 1,024

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

f(x) = x^3 + x^2 - x

f(4) = ?

Step 02:

If x = 4

f(4) = (4)³ + (4)² - 4

= 64 + 16 - 4

= 76

The answer is:

f(4) = 76
