Question

Describe the graph of the function y=x+3

Answer 1

The graphical is radical function sqrt(x) shifted 3 units left

Explanation:

The argument of the radical function is x+3, this means, that if x=-3, then y=0 since sqrt(0)=0

The parent function y=sqrt(x), something simmilar ocurrs, y=0 when x=0

This is the key difference between the two given functions.
