y-axis
One intercept of the y-axis and infinitely many of the x-axis.
It is the y intercept
An even function is symmetric about the y-axis. The graph to the left of the y-axis can be reflected onto the graph to the right. An odd function is anti-symmetric about the origin. The graph to the left of the y-axis must be reflected in the y-axis as well as in the x-axis (either one can be done first).
They are at (0, y) on the Cartesian plane where y is the vertical y axis. For any function you would have to solve the function for the value of y when x is zero - and then the coordinates would be (0,y) For the x (horizontal) axis, which is equivalent to the function y = 0, they would be (0,0), i.e. when x is zero, y is zero.

When a function is graphed, the dependent variable is usually measured along the y-axis. This is because y is the function of x.

is shows the point where a graph crosses the y-axis
All y-values in the function are multiplied by -1. This function is 'flipped' over the x-axis.
Reflection about the y-axis.
No. It depends on the function f.
If the function is in this form: y = mx + b Then b is the y-intercept. For example if the function is y = 2x + 4 then the y-intercept is 4.
