Answer:
y=1/2x²
Step-by-step explanation:
y=2x-²
y=1/2x²

At this point in time, you can use a technique called cross-mutiplication, where you say that

, and

at this point in time, you can devide each side by 8 and solve
The answer it Curve Fitting or Arc but I think Curve Fitting just good luck
A.) Simplifying the equation would lead you to 15x^2-3x+9
b.) You know your answer is correct because you're adding the two polynomials together. 9x^2+6x^2 is 1tx^2. Now you have 2x-5x and since the negative is bigger, you get -3x. Then 5+4 is 9. You have no like terms therefore your answer is 15x^2-3x+9
