Answer:
The answer is 19.
Step-by-step explanation:
Evaluating a function, f(x), at a specific point (x = -2), is the same as replacing x in the function with the point we're evaluating it at. So in this case, f(x) = 11 – 3x + 2, replacing x which is being multiplied by 3 (very important to understand it's being multiplied. Simply replacing it like 11 – 3-2 + 2 is incorrect.) gives 11 - 3*(-2) + 2. Following the order of operations, first we multiply, which gives 11 - (-6) + 2. Since subtracting a negative number is the same as adding a positive number, this expression becomes 11 + 6 + 2, which becomes 17 + 2, and finally 19.
