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:

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
