Module 1 Topic 1 Practice Test

Angela’s grandfather gave her all the cash he had in his pocket to buy raffle tickets that cost $1 each for her cheer leading fundraiser. Identify the independent quantity and dependent quantity in the problem situation. Independent Quantity Amount of money in Angela’s grandfather’s pocket Dependent Quantity Number of raffle tickets purchased Sam rode in a hot air balloon. After the balloon began its initial descent, it stayed in the air at a constant height for a while, then it continued its descent toward the ground. The graph shown represents this situation. The independent quantity is time, measured in minutes.The dependent quantity is height from the ground, measured in feet. Determine whether or not the relation is a function. Yes No I don't know Determine whether the relation is a function. Yes No I don't know Select all the function families that are both increasing and decreasing for the same function. Choose all that apply. Linear Functions Quadratic Functions Exponential Funcitons Linear Absolute Value Functions Select all the function families whose graphs consist only of lines. Choose all that apply Linear Functions Quadratic Functions Exponential Functions Linear Absolute Value Functions Thomas knows there is a relationship between the time traveled in a car and the total amount of miles traveled. Identify the independent quantity and the dependent quantity in the problem situation. Independent Quantity Time Traveled Dependent Quantity Miles Traveled David rode his bike to the park. After staying at the park for a while, he continued his ride to the grocery store. The graph shown represents this situation. The independent quantity is time, measured in minutes. The dependent quantity is the distance from home, measured in miles. Determine whether or not the relation is a function. Yes No I don't know Determine whether or not the relation is a function. Yes No I don't know Select all the function families that have an absolute maximum or minimum. Choose all that apply. Linear Functions Quadratic Functions Exponential Functions Linear Absolute Value Functions Select all the function families whose graphs are curves. Choose all that apply.
