Nonlinear Graphs Homework Name: ____________________ Literacy Why do we call quadratic equations quadratics when quad usually means four? Research What shape would a graph take if it’s highest power was 4? What about 5? Memory Substitute the x values into the equation of the graph in order to get the y values. Skill Practice Match the graphs to their corresponding equations. y = 2x y = 2x2 y = 2x3 y = 2/x Sketch graphs of the following, using the table of values: 1) 2) 3) Challenge Sketch the graphs of: y = 1/x2 y = 1/x3 y = 1/x4 Stuck? Try using geogebra.org to help you  Describe the shapes of the graphs! x -2 -1 1 2 3 y = x2 - 3   x -2 -1 1 2 3 y = x3 + 2x   x -3 -2 -1 -0.5 0.5 1 2 3 y = 3/x
