How do you writer this function in standard form??

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.
