Alejandra spent her birthday money on a video game the cost 24$, a controller for 13$, and a memory card for 16$. The total tax was 3$. Write and solved a subtraction equation to find how much money Alejandra gave the cashier if she received 4$ in change

Given:

The equations of parabolas in the options.

To find:

The steepest parabola.

Solution:

We know that, if a parabola is defined as

Then, the greater absolute value of n, the steeper the parabola.

It can be written as

where , the smaller absolute value of p, the steeper the parabola.

Now, find the value of |p| for eac equation

For option A,

For option B,

For option C,

For option D,

Since, the equation is option A has smallest value of |p|, therefore, the equation represents the steepest parabola.

Hence, the correct option is A.
