A graph represents a function only if every vertical line intersects the graph in at most one point. Example 1 : Use the vertical line test to determine whether ...
1 Answer ; y -axis, then this ; y -value is equal to ; b . Otherwise you fill in the equation y=mx+b with the values for one of the points: y1=mx1+ ...
Step 2 : We have to check whether the vertical line drawn on the graph intersects the graph in at most one point. Step 3 : In the above graph, the vertical line intersects the graph in more than one point (three points), then the given graph does not represent a function.

Step 1 : Draw a vertical line at any where on the given graph. Step 2 : We have to check whether the vertical line drawn on the graph intersects the graph in at most one point. Step 3 : In the above graph, the vertical line intersects the graph in more than one point (three points), then the given graph does not represent a function.
A relation is classified as a function if, for every input, there is at most one output. One way you can check this is by the vertical line test (imagine a ...

An effective tool that determines a function from a graph is "Vertical line test". The following are the steps of vertical line test : Step 1 : Draw a vertical line at any where on the given graph. Step 2 : We have to check whether the vertical line drawn on the graph intersects the graph in at most one point. Step 3 :
About "Find values of functions from graphs" Find values of functions from graphs : Here we are going to learn how to find values of function from graph. If a point (x, y) is on a function f, then f(x) = y. In other words, y is the output of f when the input is x.
Recognizing functions from graph. CCSS.Math: 8.F.A.1. , HSF.IF.A.1. Transcript. Checking whether a given set of points can represent a function.

Aug 26, 2013 · To find the equations of the line: The line passes through (0, 2) hence the y-intercept is 2. In the equation f (x) = ax + b, b is the y-intercept hence the equation is now f (x) = ax + 2. To find x we use point A. We substitute 10 for f (x) and 2 for x. This means we now have 10 = 2a + 2. Solving for a, we have 8 = 2a or a = 4.
