What is the value of f(x) when x = 5 from the equation f(x) = 2x - 3?

-8
7
8
-7

The correct answer is: 8

To find the value of f(x) when x = 5, we need to substitute 5 in place of x in the given equation f(x) = 2x - 3. Therefore, f(5) = 2(5) - 3 = 10 -3 = 7. This means that when x=5, the value of f(x) is 7. Option A, -8, is incorrect because when we substitute x=5 in f(x) = 2x -3, we do not get -8. Option B, 7, is the correct answer for when x=1, but not for when x=5. Option D, -7, is also incorrect because when we substitute x=5 in f(x) = 2x -3, we do not get -7. Therefore,
