The function y = x is the graph that passes from the points (-1, -1), (0, 0), and (1, 1)
The function y = 4x is the graph that passes form the points (-1, -4), (0, 0), and (1, 4)
Sketch these graphs in a same x and y coordinate system, and you can see both of them
Test it by the vertical line test. That is, if a vertical line passes through the two points of the graph, this graph is not the graph of a function.
When a function is multiplied by -1 its graph is reflected in the x-axis.
A vertical line test can be used to determine whether a graph is a function or not. If a vertical line intersects the graph more than once, then the graph is not a function.
A linear function.

No, a circle graph is never a function.
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.
Yes the graph of a function can be a vertical or a horizontal line
Yes the graph of a function can be a vertical or a horizontal line
sine graph will be formed at origine of graph and cosine graph is find on y-axise
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.
If you mean y = 4x+2 then it is the linear equation of a straight line
A graph is a function if every input (x-value) corresponds to only one output (y-value). One way to check for this is to perform the vertical line test: if a vertical line intersects the graph at more than one point, the graph is not a function.
Test it by the vertical line test. That is, if a vertical line passes through the two points of the graph, this graph is not the graph of a function.
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
