Answer: -5
Explanation: In this problem, we're given the function f(x) = -2x + 5 and we are asked to find f(5).
To find f(5) or the value of the function when x = 5, we simply substitute 5 in for x in our function.
So we have f(x) = -2(5) + 5 or -10 + 5 which equals -5.
So f(5) or the value of the function when x = 5 is -5.
