Question

Help me understand this

Answer 1

So the graph is f(x) right? So x is any number along the x axis. so youre finding the y value for f(7)

Answer 2

"Find the value of f(7)" means find the value of y when x=7.

It means this because y = f(x), and when x=7, the equation is y = f(7). (7 is put where x was in f(x).)

The graph shows you y=0 where x=7.

The value of f(7) is 0.
