the vertex of this parabola is (4, -12) what is the axis of symmerty?

Sagot :

Answer: x = 4

Step-by-step explanation:

parabolas are symmetrical over their vertex, so a vertical line going through the vertex would be the axis of symmetry

because x = __ gives a vertical line, x = 4 is your axis of symmetry

*the x-value in the vertex of a parabola is always the axis of symmetry
