MAC 1147 (3069) - Quiz #3 Name: Key For full credit, you must show all work and circle your final answer. 1 Rewrite the expression using negative exponents. (1 point) 2 - x ( x + 1) 2 3 2 - x ( x + 1) 2 3 = (2 - x )( x + 1) - 2 / 3 . 2 Identify all x or y intercepts and graph the equation. On the graph, label the intercepts you found. (2 points) y = x 3 - 1 x -intercepts: 0 = x 3 - 1 = 1 = x 3 = x = ± 1. So, the x -intercept is (1 , 0). y -intercept: y = 0 3 - 1 = - 1. So, the y -intercept is (0 , - 1). 3 Find the slope-intercept form of the equation of the line passing through the points. Graph the line
