Final answer:
To determine ƒ(5) for the function ƒ(x) = -2x - 5 + 7, we substitute 5 into the equation, resulting in -8.
Step-by-step explanation:
To find the value of the function f(x) = -2x - 5 at x = 5, we simply substitute x with 5 in the function:
f(5) = -2(5) - 5 + 7
Then we perform the multiplication:
f(5) = -10 - 5 + 7
And follow with the addition and subtraction:
f(5) = -15 + 7 = -8
Therefore, ƒ(5) equals -8.
