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
Yes it is a function because none of the x-values belong to 2 different y-values. The domain is -4, -3, -2, 0, 2, 3. The range is -3, -1, 0, 2, 3. The value of y when x=2 is -3 because when the x-value was 2 the y-value the point was on equaled -3.
