Definite Integrals Questions and Answers

Calculus
Definite IntegralsGiven the graph of y f x shown as a red dashed curve drag the green movable points to draw the graph Notice that you can control the positioning of the reflective function with the coordinate labeled Drag Function and contra the width of the reflection with the coordinate labeled Control Width Because the green curve starts in the same position as the red dashed curve you may need to drag the green curve away from its initial position in order to see the red dashed curve Provide your answer below 10 Drag Function 5 10 Control dth 0 5 10
