Which of the following equations describes the graph?

The equation that represents the graph is:

We know that the general quadratic equation of the type:

is a upward or a downward parabola depending on a.

If a>0 then the parabola is a upward open parabola.

and if a<0 then the parabola is a downward open parabola.

Hence, the option:

Hence, the two options are discarded as there leading coefficient is negative but the parabola is open downward.

Hence, we are left with

From the graph, we have when x=0 we have f(0)= -3

Hence, the only option we are left with is:

( Since, in the option:

    at x=0 we have y=3≠ -3  )

answer: -8.2562234e+13

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
