Answer:
f(1)=-4
Step-by-step explanation:
f(1) means what is the y in the point on the curve of f so that x=1.
So I go to x=1 on the x-axis.
So I go right one from the origin.
I notice the curve is below the x-axis so I go down to the curve til I get to the curve.
Once I get to the curve, I look at the y-axis to tell what that number is for that ordered pair there at x=1.
That y-value is -4.
A graph/picture is probably worth a lot more to you then my words.
Other examples:
f(2)=-5
f(3)=0
f(-1)=4
f(-2)=5
f(-3)=0
