If the parents function is y4x which is the function of the graph?
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
How can you tell whether a graph is a function or not?
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.
What is a function rule?
how you get x to equal y. it is usually in a graph
Can the graph of a function yfx always cross the y-axis?
No. It depends on the function f.
How do you graph x squared equals y squared?
The same as you would graph x=y. If you take the square root of both sides you get x=y __________________________ You also need to add the graph of x=-y, since x2=y2 is the same as x=+/-y. For example, (-1,1) is a solution to this equation since (-1)2=1=(1)2. You can see that x is not a function of y (and y is not a function of X) because for each value of x that satisfies the equation, there are two values of y possible. For example, (-1,1) and (-1, -1) both satisfy the equation.
