If the point (x,y) is on the graph of the even function y = f(x) then so is (-x,y)
That would depend on its original coordinates and in which direction clockwise or anti clockwise of which information has not been given.
A zero of a function is a point at which the value of the function is zero. If you graph the function, it is a point at which the graph touches the x-axis.
If the graph of the function is a continuous line then the function is differentiable. Also if the graph suddenly make a deviation at any point then the function is not differentiable at that point . The slope of a tangent at any point of the graph gives the derivative of the function at that point.
Graph is a collection of points whose coordinates satisfy a given relation.
Mark the position of the point on the graph according to the coordinates of the point that are given (or calculated).
You cannot, necessarily. Given a graph of the tan function, you could not.
Their first coordinates are positive and their second coordinates are negative.
At the given coordinates where the x and y values intersect
Draw a graph of a given curve in the xoy plane. Now draw a vertical line so that it cuts the graph. If the vertical line cuts the graph in more than one ordinate then given graph is not a function. If it cuts the graph at a single ordinate such a graph is a function.(is called vertical line test)
A function must have a value for any given domain. For each edge (or interval), the sign graph has a sign (+ or -) . So, it is a function.
Graph each "piece" of the function separately, on the given domain.
It is where the x and y coordinates intersect.
The coordinates of the points on the curve represent solutions of the equation.

A vertical shift is the vertical motion of a function on a graph through manipulation of the y-coordinates, while simultaneously leaving the x-coordinates unchanged. A horizontal shift is the opposite of a vertical shift, in that the function is moving horizontally by manipulating the x-coordinates and leaving the y-coordinates unchanged.
