Answer:
Step-by-step explanation:
The three does nothing. When the equation is y = 3(x - 2)(x - 2) then the graph is stretched. See below for the imported graph.
To make this graph = 0 you make (x - 2) = 0
x - 2 = 0 Add 2 to both sides
x - 2 + 2 = 0 + 2 Simplify
x = 2
As you can see from the graph, the lowest point is 2,0. It just touches the x axis. That happens because there are 2 roots, both the same.

Red: (x - 2)(x - 2)
Blue:3(x - 2)(x- 2)

Answer:
20 comic books
Step-by-step explanation:
Let us first <u>set up a variable</u>, x, for the number of books that Zoe has. If Jared has 12 more comics than Zoe, he would have x+12 books.
Given that Zoe and Jared have a total of 28 comic books, let us write an <u>equation</u> and solve for x:
Now that we have a <u>simplified</u> version of the equation, let us solve for x by <u>isolating the variable</u> on the left side:
We now know that x=8, and also that Jared has x+12 books. To find the number of comic books Jared has, let us <u>add</u> 12 to x:
Therefore, Jared has 20 comic books.
