A.
We can rewrite the squared in two ways.
The first way is to rewrite it as a multiplication, this is:
The second way to rewrite the squared is by using the formula for this kind of product:
B.
Once again we can find the final result using each of the options given in part A, for the first option we have:
For the second option we have:
No matter which way we choose the answer for the squared is:
Answer:
To graph (like the provided picture) you must understand y=mx+b. Your m would stand for your slope which you need to determine with rise over run. Rise over run can be done by finding a place where both the x and y values are lined up. (0,-2) can be used as an example from the picture. You then want to find the next point where the x and y values line up which (-2,1) can be used. Go up 3 units and go to the LEFT 2 times which makes this a negative run. The slope would then be represented as -3/2.
Your x value stands for your x-value moving up or down while you b value stands for your y-intercept which point (0,-2) is represented as. Y represents the y value after the equation is plugged in with x and solved.
