Answer 2

`y=7x^2`

Explanation:

The parent function is
`y=x^2`

Now, the transformation rule is

• Whenever the parent function f(x) is scaled vertically by k units then the translated function is kf(x)

Here, the parent function is scaled vertically by a factor of 7 . Hence, k = 7

Therefore, the equation of the new parabola is
`y=7x^2`
