Graphs That Are Not Functions Examples. For a basic exponential function of the form 𝑏𝑥 the y intercept is 1. A function is defined as an equation where every value of x has one and only one value of y.
Determine if a graph is a function or not learn with flashcards games and more for free. As pictured the x value 3 corresponds to more than one y value. Breaks gaps or points at which they are undefined.
In the graphs below the function is undefined at x 2.
For a basic exponential function of the form 𝑏𝑥 the y intercept is 1. In this case symmetry is apparent so proceed to step 3. In the graphs below the function is undefined at x 2. Sketch both graphs on the same coordinate grid.
