Question

I need help. I do NOT understand this Algebra 2 college level stuff.

Answer 1

1. Your friend runs up to you, scared that he is not ready for the upcoming quadratics test. To help him study, you will create four different quadratic functions. Then demonstrate to him how to rewrite each function as a group of factors, if possible.
o The function f(x) is a difference of squares.
o The function g(x) is a sum of squares.
o The function h(x) is a perfect square trinomial.
o The function j(x) can only have a GCF factored out of it.

2. Given the function k(x) = x2, compare and contrast how the application of a constant, c, affects the graph. The application of the constant must be discussed in the following manners:
o k(x + c)
o k(x) + c
o k(cx)
o c • k(x)

3. Explain the grouping method of factoring. Describe a scenario when the grouping method would be preferred over other methods and provide an example of this type of problem.

4. Graph one of your 2nd degree functions from question. Identify which function you used and the key features of your graph. Explain how to find them algebraically.

5. Using your graph from question 4, describe if the average rate of change is increasing or decreasing, from left to right. Justify your observations with calculations

Answer 2

Which part?

Answer 3

1-5

Answer 4

So for the first part, you have to come up with some functions that fit those conditions, then factor them! Just looking at the words, what do you think the difference of 2 squares is?

Answer 5

A square is something that is squared, like x^2, 2^2, (3x)^2 etc. and the difference just means one subtracted from another. If one of the two things your squaring has to be a variable (x,y,...) and one has to be subtracted from the other, can you come up with a function?

Answer 6

~~one of the two things you're squaring

Answer 7

did you find the answers? can you copy and paste them on here please!

Answer 8

Can you give us the answers?

Answer 9

what are the answers?! we need em too.
