f(x) = 2(x + 5)(x + 1) function models the data shown on the graph.
How do you identify a function shown in a graph?
Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.
How do you find a function?
When we have a function in formula form, it is usually a simple matter to evaluate the function.
