Sample AnswerWhen a linear function is expressed in different forms, its slope and yintercept remain the same The slope from the equation is 1, and the yintercept from the equation is 3 The slope from the table is 1, and the yintercept from the table is −3 These are not the same functionsThe graph of the function is the set of all points (x,y) ( x, y) in the plane that satisfies the equation y= f (x) y = f ( x) If the function is defined for only a few input values, then the graph of the function is only a few points, where the x coordinate of each point is an input value and the y coordinate of each point is theUse a Table of Values to Graph the Equation y=x3 y = x − 3 y = x 3 Substitute −2 2 for x x and find the result for y y y = (−2)−3 y = ( 2) 3 Solve the equation for y y Tap for more steps Remove parentheses y = ( − 2) − 3 y = ( 2) 3 Subtract 3 3 from − 2 2
