Solving Radical Equations Graphically
Given the function f(x) √4-2x find x when f(x) 6 using your graphing calculator. Then follow
the steps below to show the intersection graph on the computer. [Hint: Use the following window on
your graphing calculator: Xmin=-18, Xmax = 10, Ymin=-10, Ymax = 10]
1. Write the point of intersection as an ordered pair below. Round the value of x to two decimal
places as needed. If the point of intersection does not exist, enter DNE
2. Use the Line Tool to draw the Horizontal Line y 6.
3. Use the Square Root Tool to draw f(x)= √4 2x. To draw this function, first plot the point
furthest to the right, followed by one more point.
4. Use the Point Tool to identify the point of intersection if it exists.
