We want to find all the solutions to the equation [tex]f(x)=0[/tex]. Wich means that we want to find all values of [tex]x[/tex] such that [tex]y=0[/tex] (recall f(x)=y).

By looking at the graph, when does [tex]y=0[/tex]? That's right, exactly over the X axis!

The solutions to the equation are the X coordinates where the graph crosses the X axis.

They are -5,-2 and 4.

Step-by-step explanation:

The open circle means that it isn't equal to so x is less than two because of where its headed on the line

The second one is equal to becasue it's filled in. Once again X is less than this number beacause of which way it is going on the graph

for the first one it would be x < 2
