How did you calculate f(0) ?
To find f(2), look at your graph and see what the value of y is on the curve when the value of x is 2.
y = f(2)
If you want to define the equation of the parabola, you could use a point on the curve.
You can see the vertex is at (2, -1).
Use , vertex (2, -1) for (h, k), and some other point on the curve find that a = 1. Then the equation becomes:
Now, to find f(2):
