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.
