Consider the following ingredients:

1 cup butter, softened

• 1 cup white sugar

• 1 cup packed brown sugar

• 2 eggs

• 2 teaspoons vanilla extract

• 1 teaspoon baking soda

• ½ teaspoon salt

• 3 cups all-purpose flour

• 2 cups semisweet chocolate chips

Describe what the "output" of this recipe would be and why this would be the dependent variable.

Answer explanation

These ingredients (inputs) could make chocolate chip cookies, so that illustrates the "output" of the recipe. What the recipe makes depends on the ingredients that are used, so the cookies would be the dependent variable.

Consider the following ingredients:

• 1 (15 ounce) can pumpkin puree

• 1 (14 ounce) can Eagle Brand Sweetened Condensed Milk

• 2 large eggs

• 1 teaspoon ground cinnamon

• ½ teaspoon ground ginger

• ½ teaspoon ground nutmeg

• ½ teaspoon salt

• 1 (9 inch) unbaked pie crust

Describe what the "input" of this recipe would be and why this would be compared to the independent variable of a function.

Answer explanation

The ingredients represent the input variables (or x-values) and the outcome would be pumpkin pie. We choose our ingredients based on what we want to make, so the ingredients represent the independent variables in a function.
