Question

May you please do # 17, 9 ,4 , 7 please!!!

Answer 1

7) Vertex = V(2,3)

9) Vertex = V(2,1)


17) The smaller the absolute value of the coefficient of x², the larger is the opening of the parabola. (to compare, just take the absolute value of a)

Coefficients are (5), (-3) and (1):

Widest: f(x) =x², followed by f(x) = -3x²  and the narrowest is f(x) =5x².
