Answer:
f(3) = 1
Step-by-step explanation:
f(x) = x² - 2ˣ
You are solving for f(3). Plug in 3 for x in the equation:
f(3) = (3)² - (2)³
Simplify. First, simplify each number by solving the powers, then subtract:
f(3) = (3 * 3) - (2 * 2 * 2)
f(3) = (9) - (8)
f(3) = 9 - 8
f(3) = 1
f(3) = 1 is your answer.
