Question

How do you find the function values f(-1/2) given f(x) = -4x?

Answer 1

+2

Explanation:

The expression `f(x)` basically means "this is what you do with `x`"

So if you have `f(-1/2)` it is stating that what you did with `x` you now do the same thing with `-1/2`

So if `f(x)=-4x`

Then `f(-1/2)=-4(-1/2) = +2`
