Algebra/Trig Review - Pauls Online Math Notes - Lamar University

Algebra/Trig ReviewFor the equation listed here the hyperbola will open left and right. Its center is(-1, 2). The two vertices are (-4, 2) and (2, 2). The asymptotes will have slopesHere is a sketch of this hyperbola.2± .310. y = xSolutionThere isn’t much to this problem. This is just the square root and it’s a graph that youneed to be able to sketch on occasion so here it is. Just remember that you can’t plugany negative x’s into the square root. Here is the graph.11.y = x3SolutionAnother simple graph that doesn’t really need any discussion, it is here simply tomake sure you can sketch it.© 2006 Paul Dawkins 28http://tutorial.math.lamar.edu/terms.aspx
