Question

Please please help! I don't understand!

Answer 1

The first graph is an odd function. y = x
x is to the first power which is odd and it is symmetric across the origin.
The second graph is neither. The parent function is y = x^3 but shifting it down makes it not symmetric to the origin.
The third graph is even. The parent function is
y = x^2. It is symmetric across the y-axis.
