Vertical line tests a visual way to determine that the curve is a graph of a function or not. Models O y x If some vertical line intersects a graph in two or more points, the graph does not represent a function. If it is, use the graph to find: (a) The domain and range (b) The intercepts, if any (c) Any symmetry with respect to the x-axis, the y-axis, or the origin H-2,-1) Is the graph that of a function? So the vertical line test essentially says that if we draw a vertical line that's parallel to the Y axis coming like this along the left side of the graph and move it all the way across to the right, the graph is a function of X. Vertical line test In mathematics, the vertical line test is a test to determine if a curve is a relation or graph of a function when the function's domain and range correspond to the x and y axis of the Cartesian coordinate system. 5.1k plays . All quizzes. multiple ways to do it:-x values are domain, y values are range-if it is a line SEGMENT, the domain would be first x point GREATER THAN OR EQUAL TO x GREATER THAN OR EQUAL TO the second x point (and same thing for range, except use y) If it is, state…, EMAILWhoops, there might be a typo in your email. PLAY. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x -axis. If it is, use the graph to find (a) its domain and range. You know that, and because it's not a function of X, we do not answer the other parts of the question"}, Vertical Line Test: Domain and Range Use the VerticalLine Test to determ…, ? two times. Preview this quiz on Quizizz. No, because the vertical line test shows there are repeating input values. Another way to identify the domain and range of functions is by using graphs. If you think about it, the vertical line test is simply a restatement of the definition of a function. (c) any symmetry with respect to the x-axis, y-axis, or the origin. states that if a vertical line intersects the graph of the relation more than once, then the relation is a NOT a function.
