Final answer:
To find f(3) for the function f(x) = 3x^2 + 8, substitute 3 for x, resulting in f(3) = 3(3)^2 + 8 = 27 + 8 = 35. Hence, the correct answer is A) f(3) = 35.
Step-by-step explanation:
When we want to find the value of a function f(x) at a specific point, say x = 3, we substitute that value into the function and perform the necessary calculations. In this case, f(x) = 3x^2 + 8, to find f(3), we substitute 3 for x and calculate accordingly.
The computation would be as follows: f(3) = 3(3)^2 + 8 = 3(9) + 8 = 27 + 8 = 35. Therefore, the correct answer is A) f(3) = 35.
