Use the graph below to fill in the blank with the correct number:
f(1) = _______

we know that
[tex]f(1)[/tex] is the value of the function when the value of x is equal to [tex]1[/tex]
In this problem, look on the graph to see
For [tex]x=1[/tex]
the value of the function is [tex]f(1)=-2[/tex]
therefore
the answer is
[tex]f(1)=-2[/tex]
