87 dollars hope this helps I can’t really show you how to do it though because I think it will over complicate the problem but
A) Your primary concerns are the points B and E, so y> .5x+4 and y>or= x-4B) choose one or both points, and enter them into the equations. If the statements are true, then the equations work
for problem C So, any point in the shaded area, but not on the line, are valid points for Natalie's school
Oh shucks man, I'm sorry bout that
Let

. Then

Meanwhile, since

, you have

.
It follows that

,

, and

, so that the quadratic fit for

that satisfies the given points is

Note that this is just the second-order Taylor polynomial for

about

.
