Final answer:
To find f(4) for the function f(x) = 2x^3, you calculate 4 cubed (64) and then multiply by 2 to get 128. Therefore,
the answer is 128, option c.
Step-by-step explanation:
You have asked to find the value of f(4) using the function f(x) = 2x^3. To do this, you substitute the value of 4 into the function:
f(4) = 2(4)^3
To solve, first compute the cube of 4:
4^3 = 4 × 4 × 4 = 64
Then multiply this result by 2:
f(4) = 2 × 64 = 128
So, the value of f(4) is 128, which corresponds to option c.
