Which statement describes the effect on the parabola y = x2 - 1 when it is changed to y = x2 +6?
zlopas [31]

Initial:

y=x^2-1

Changed to:

y=x^2+6

As you can see the change is: from -1 to +6.

In a equation as follow:

y=x^2+k

The k is a transformation that moves up or down the graph of the function. If k is changed to a less value the graph moves down, If k is changed to a greather number the graph moves up.

In this case the graph moves up

To find the number of units the graph moves find the difference betwwen values of k:

6-(-1)=7

Then, the parabola y=x²-1 is moved 7 units up when it is changed to y=x²+6
