Method1 Particularly to this problem, it is an even function in x ie if you replace x by − x, the equation still remains the same Hence, it must be symmetric about the line x = 0 or, the y axis Method2 Transformations Draw y = x 2 Stretch it vertically to get y = 2 x 2 Now shift it up by 8 units to get y = 2 x 2 8Y = 2x 2 y = 2 x 2 Use the slopeintercept form to find the slope and yintercept Tap for more steps Find the values of m m and b b using the form y = m x b y = m x b m = 2 m = 2 b = 2 b = 2 The slope of the line is the value of m m, and the yintercept is the value of b b Slope 2 2How to Graph a Linear Inequality First, graph the "equals" line, then shade in the correct area Rearrange the equation so "y" is on the left and everything else on the right Plot the " y= " line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>) or below the line
