Which is f(-3) for the quadratic function graphed?
(a) -9, (b) -3, (c) 0 (d) 9

Solution:

Quadratic equations are equations that have a degree equal to two and are represented by a parabola on the cartesian plane.

From the given graph of the quadratic equation, it is clear that it is an upward parabola, with its vertex at (-3, -9).

Looking at the graph, when we check the y-coordinates corresponding to x = -3, we get f(-3) = -9.

Hence, from the given graph of the quadratic function, we have f(-3) = -9.

Which is f(-3) for the quadratic function graphed? (a) -9, (b) -3, (c) 0 (d) 9

Summary:

Option (a) -9, from the given graph of the quadratic function, we have f(-3) = -9.
