Question

The parabola y=x2 is scaled vertically by a factor of 7. What if the equation of the new parabola

Answer 1

`f(x) = x^2`

And we want to scale vertically this parabola by a factor of 7. So then we need to multiply our function by the factor:

`g(x) = k f(x)`

And then function would be:

`g(x) = 7x^2`

Explanation:

For this case we have the original function given by:

`f(x) = x^2`

And we want to scale vertically this parabola by a factor of 7. So then we need to multiply our function by the factor:

`g(x) = k f(x)`

And then function would be:

`g(x) = 7x^2`
