Question

If the function graphed is f(x), find f(1)

Answer 1

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
