Please help, it’s math and it’s easy! explantion needed

The equation of the parabola is:

Step-by-step explanation:

You can use the "vertex form of a parabola" to easily write the equation for it.

The vertex form of a parabola contains explicitly the coordinates of the vertex in it It looks like:

In this case, we know the coordinates of the vertex: (3,-2), so we can simply replace them in the formula, which leaves us with just one unknown the resolve; "the multiplicative factor "".

Now, we can find the multiplicative factor by using the information that the parabola goes through the point (0,-7) Its y-intercept:

Therefore, the complete equation of the parabola becomes:

i dont know sorry

step-by-step explanation:

i think is g(1)=-1.

hope that i can
