Question

For y = x^2 + 10x + 24, write the axis of symmetry, the vertex, and whether the

parabola opens up or down.

Answer 1

x= - 2

Explanation:

hello :

note : the equation of the axis symmetry for the parabola : y =ax²+bx+c

when : a≠ 0 is : x=- b/2a

in this exercice : a=1 and b=10

so : x= -10/2 = -5
