Graphing Inequalities Graph the solution set for shade above (-2,3) (1.5,1.25) shade below On your calculator: Move the cursor to the left of y1 and use the enter key to change its symbol. Shade above Shade below The INTERSECT function will still find intersection points.

Linear Programming A nutrition center sells health food to mountain climbing teams. The Trailblazer Mix contains one pound of corn cereal mixed with four pounds of wheat cereal and sells for $9.75. The Frontier Mix contains two pounds of corn cereal mixed with three pounds of wheat cereal and sells for $9.50. The center has 60 pounds of corn cereal and 120 pounds of wheat cereal available. How many packages of each mix should be sold for the center to maximize its income? What is its maximum income? What are we really trying to do? maximize income What are the limitations/constraints? corn wheat x = trailblazer mix y = frontier mix x and y must not be less than zero!

Test each vertex in the income equation to find the maximum: Shade the solution set Shade everything but the solution set 2 graphing options The vertices of the region created by the solution set are the potential solutions. intersection (12,24) CALC:INTERSECT (30,0) x-intercept y-intercept (0,30) CALC:ZERO CALC:VALUE:0 Be sure you use the correct line! Be sure you use the correct line! (0,0) Test each vertex in the income equation to find the maximum: (0,0) (12,24) (0,30) (30,0) The center should sell 12 Trailblazer and 24 Frontier for a maximum income of $345.
