Find the area of the polygon with the given vertices. NC (– 2, 1), P(3, 1), Q(3,-1), R( – 2, -1)
what is the area in
square units.

A= w . h = 10

Step-by-step explanation:

Look at attached graphic.

It's a rectangle.

width (in x axe) = length between 3 to -2 = 5

height (in y axe) = length between 1 to -1 = 2

ANSWER

The y-intercept is (0,-12).

The x-intercepts are (1,0),(2,0) and (6,0).

EXPLANATION

The given polynomial function is

To find the y-intercept, we substitute x=0 to get:

This simplifies to

Therefore the y-intercept is (0,-12).

To find the x-intercepts we need to factor completely the given polynomial.

We use synthetic division to get the remaining factors. We carried the division in the attachment.

This implies that

The complete factorization is:

For x-intercepts, f(x)=0.

This implies that, x=1,2,6.

The x-intercepts are (1,0),(2,0) and (6,0).
