To solve this question, we must evaluate the function f(x) for an x value of -2. What this means is we must replace each variable "x" in the f(x) equation with a (-2) and evaluate.
f(x) = 2x - 5
Replace each variable x with the x-value -2.
f(-2) = 2(-2) - 5
To simplify, we should first use multiplication, as outlined by the order of operations (PEMDAS) - parentheses first, exponents next, then multiplication and division, and finally addition and subtraction.
f(-2) = -4 - 5
Finally, we should compute the subtraction on the right side of the equation.
f(-2) = -9
Therefore, your answer is -9.
Hope this helps!
