A store uses the expression -2p + 50 to model the number of backpacks it sells per day, where the price, p, can be anywhere
2 answers:
Since the term 2p is negative, the greater is gets, the smaller the final result.
So, you want 2p to be as small as possible, so that you take away as little as possible from 50.
In particular, 2p is as small as possible if p is as small as possible, and our lesser option is 9.
So, if p=9, the revenue is

Answer:
Step-by-step explanation:
If you plot the vertex and the point, you see that the point is above the vertex. Therefore, this is a positive parabola with the work form of
We have values for x, y, h, and k. Let's write the equation of the parabola, put it into function notation, then find another x value at which to evaluate it.
and
and
8 = 9a - 1 and
9 = 9a so
a = 1. The equation of the parabola in function notation is
Since the vertex is at (3, -1) it would make sense to evaluate the function at x values close to the vertex. Let's evaluate the function at an x value of 4:
and
and
f(4) = 0. That means that another point on this parabola will be (4, 0).
