Question 1) Function defining the table:
From the table the x-intercepts are -2 and 1. This means the factors are:
(x+2) and (x-1)
Let

The point (-1,-1) satisfy this function since it is from the same table.

Therefore the function is

We expand to get:

The standard form is:

Question 3) Parabola opening up
The x-intercepts are x=3 and x=7
The factors are (x-3), (x-7)
The factored from is

The curve passes through (5,-4)

The equation is:

Expand:


This is the standard form:
Question 3) Parabola opening down:
The x-intercepts are x=-5 and x=1
The factors are (x+5), (x-1)
The factored form is

We expand to get:


This is the standard form.
The degree of that polynomial is 5.. it's always the highest exponent in the expression. So choice D
Answer:
f
Step-by-step explanation:
Green vines attached to the trunk of the tree had wound themselves toward the top of the canopy. Ants used the vine as their private highway, avoiding all the creases and crags of the bark, to freely move at top speed from top to bottom or bottom to top depending on their current chore. At least this was the way it was supposed to be. Something had damaged the vine overnight halfway up the tree leaving a gap in the once pristine ant highway.
