What is the equation of the graphed function?

enter your answer in the box.

f(x)=

Step-by-step explanation:

It's the parabola - the graph of a quadratic function.

The vertex form of an equation of a parabola:

(h, k) - vertex

We have the vertex in (-3, 0) → h = -3, k = 0. Substitute:

Choice one point from the graph (-1, 4). Substitute:

             divide both sides by 4

Finally:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
