question 16 of 25
evaluate the function below for x = 3.
f(x) = 2x³ - x² - 4x + 9

a. 204
b. 9
c. 60
d. 42

Explanation:

Step1: Substitute x=3 into F(x)

$F(3) = 2(3)^3 - (3)^2 - 4(3) + 9$

Step2: Calculate each term

$2(27) - 9 - 12 + 9 = 54 - 9 - 12 + 9$

Step3: Compute the result

$54 - 9 - 12 + 9 = 42$

Answer:

D. 42
