f(x) = 2 x - 5
f (4) = 2 * 4 - 5 = 8 - 5 = 3

f(x) = 2x - 5 and find the value of f(4):
*Take 4 and replace it with the "x" variable in the function:
f(4) = 2(4) - 5
f(4) = 8 - 5
f(4) = 3

F(x)=2x-5
F(4)=2*4-5 Replacing 4 in place of X
=8-5
=3

If f (x) = 2 x - 5, the value of f (4) is what?
f(4) = 2(4) -5 = 8-5 = 3
Just replace x by 4 in these kinds of questions.

f (4) means replace x with 4.
so (2 times 4) minus 5 equals 3.
f(4)=3

X stands for a number when they give you that kind of an equation f(x) with the x inside the parentheses and the x outside along with the given f(4) then you can go ahead and replace all the x with a 4
