WebUse the vertical line test to determine if the graph depicts y is a function of x. Solution: y is NOT a function of x (as it is possible to draw a vertical line to touch the graph in more than one place.) Notice, the vertical line test has found two points on the graph { (4,2) and (4,-2)} that have the same x with different y’s. WebWhere the vertical line test tells you if the graph is a function, the horizontal deals with the inverse. We can apply the horizontal line test by drawing a horizontal line across our graph. If it touches two or more …

WebVertical Line Test. Conic Sections: Parabola and Focus. example WebVertical Line Test. The vertical line test is a method that is used to determine whether a given relation is a function or not. The approach is rather simple. Draw a vertical line cutting through the graph of a relation, and then observe the points of intersections. Horizontal Line Test. The horizontal line test is a convenient method that can … WebOne way to see the domain of a function is to sketch vertical lines and look for the intersection between the vertical line and our function. If a vertical line does not intersect the curve, that 𝑥 -value must be excluded from the domain. This function has a vertical asymptote at 𝑥 = 5. east durham college courses
