Answer:

53

Explanation:

To evaluate f(-4), we need to substitute -4 into the function f(x) = 3x^2 - 4x - 11.

1. Replace x with -4 in the function:

f(-4) = 3(-4)^2 - 4(-4) - 11

2. Simplify the expression within the parentheses:

f(-4) = 3(16) + 16 - 11

3. Evaluate the exponent:

f(-4) = 48 + 16 - 11

4. Perform the addition and subtraction:

f(-4) = 53

Therefore, evaluating f(-4) in the function f(x) = 3x^2 - 4x - 11 gives a result of 53.
