When graphing functions, we take the following steps: Find the function's domain and range and keep them in mind as you draw the curve. Find and plot the x-intercept(s) and y-intercept(s). Determine whether or not there are any holes.

Inspect the graph to see if any vertical line drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function. If no vertical line can intersect the curve more than once, the graph does represent a function.

Let f(x) = x2 - 3. Graphs of functions are graphs of equations that have been solved for y! The graph of f(x) in this example is the graph of y = x2 - 3. It is easy to generate points on the graph. Choose a value for the first coordinate, then evaluate f at that number to find the second coordinate.

To graph an equation using the slope and y-intercept, 1) Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). 2) Next, plot the y-intercept. 3) From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.

The equation is written in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept. This is a picture of a coordinate plane with the point ( 0 , ? 4 ) graphed on it.
