3) the graph of the equation y = x2 + 1 is shown. which equation will shift the graph up 7 units? a) y = x2 + 7 b) y = x2 - 8 c) y = x2 + 8 d) y = (x+7)2

C)

Step-by-step explanation:

the function

Is a parabola that crosses the y-axis at .

So in a function of the form:  , the number indicates the point at which the graph of the function crosses the y-axis.

So, to find a function that is 7 units above, we need to add 7 to the number .

In this case

so adding 7:

So the resulting function, which is 7 units above is:
