100 points<br> (algebra one)<br> describe and correct the error in comparing the graphs
Pepsi [2]

Answer:

The error made is that the graph of y=x^{2} +3 is a vertical translation up by 3, instead of down.

Step-by-step explanation:

Exponential functions, when they are graphed, use the function f(x)=a(x-h)^{2} +k.

In the equation, k expresses how much the graph shifts vertically. In this case, the function shifts vertically up by 3 from the parent function, y=x^{2}. So, the translation is actually 3 units up compared to the graph of y=x^{2}.

Hope this helps and have an amazing day!! ❤
