Answer:
C is 27 and d is 16
Step-by-step explanation:
count how many cubes are on the first level and multiple but how many it goes up too
You can factor a parabola by finding its roots: if

has roots
, then you have the following factorization:

In order to find the roots, you can use the usual formula

In the first example, this formula leads to

So, you can factor

The same goes for the second parabola.
As for the third exercise, simply plug the values asking

you get

Add 3 to both sides:

Divide both sides by 1.5:

Domain is the x-coordinate and range is the y - coordinate

B because of the y to the zero? Anyone wanna back me up?
