What is the equation of the graph below? A graph shows a parabola that opens up and crosses the x axis at negative two and negat
Anastaziya [24]

Answer:

y=(x+3)^{2} -1

Step-by-step explanation:

General equation of a parabola that opens up is y=a(x-h)^{2} +k , a>0

So equation becomes y=(x-h)^{2} +k which implies option A and option B can never be true for this parabola.

Also this parabola's vertex lies in 3rd quadrant where coordinates of both x and y will be negative.

So, the equation of parabola will be of the form y=(x+h)^{2} - k

Hence, option 4 that is y=(x+3)^{2} -1 is correct.
