Question

I'm stuck. Help please.

Answer 1

Usually you will see something like g(x) or f(x)

domain means all the x's

so, think of g(4) meaning g(x=4) and g(4 in the domain).

look for 4 on the domain side

you know that f(x) = y

range means all the y's

so its basically saying, look on the domain side for 4 and see what comes out (or =) on the range side.

in this case, it's B) 5
