Practice 7) fill in the blanks. the vertex form of a parabola is y=a(x-h)^2+k, is the vertex. the line of symmetry is x= if a> 0, the parabola and the vertex is if a< 0, the parabola and the vertex is

(h,k) is the vertex

b/2a is the line of symmetry

a > 0 parabola opens upward, vertex is a minimum

a < 0 parabola opens downward, vertex is a maximum

My first answer was deleted lolol

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
