Answer:
15
Step-by-step explanation:
In the function f(x), x is the variable. So, whatever is in the parentheses, replacing x, should replace x throughout the entire function. So, to find f(4) simply plug in 4 for x.
- First, rewrite the function with 4 as x
f(4) = 4^2 - 4 + 3
f(4) = 4^2 - 1
- Then, raise 4 to the power of 2
f(4) = 16 - 1
f(4) = 15
