Determining if a relation is a function
WebAt first glance, a function looks like a relation . A function is a set of ordered pairs such as { (0, 1) , (5, 22), (11, 9)}. Like a relation, a function has a domain and range made up of the x and y values of ordered pairs . Answer.

WebUse 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. WebSep 23, 2024 · To evaluate a function f that uses an equation for a rule, we take the input and swap it out for x in the rule. Example 2.1. 15. For the function f ( x) = 2 x, evaluate the following: f ( 3) f ( − 1) f ( 0) Solution. To evaluate f ( 3), we substitute the x in the rule that f follows with the 3.

WebThe table below represent the values of the functions h. Determine whether each function is linear, exponential, or neither. Then determine the rule for the function. If the function is neither exponential nor linear write N for the function rule. x -3; Determine if f is a linear or nonlinear function and if f is a constant function.
