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  )

step-by-step explanation:

do you have a copy of the table?

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
