Here are four graphs. Match each graph with a quadratic equation that it represents.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Graph B. | arrow_right_alt | |
Graph D. | arrow_right_alt | |
Graph A. | arrow_right_alt | |
Graph C. | arrow_right_alt |
Select all equations whose graphs have a -intercept with a positive y-coordinate.
Here is a graph of the function g given by
What can you say about the value of b? Explain how you know.
Determine the x-intercepts, the vertex, and the y-intercept of the graph of each equation.
Equal amounts of money were invested in stock A and stock B. In the first year, stock A increased in value by 20%, and stock B decreased by 20%. In the second year, stock A decreased in value by 20%, and stock B increased by 20%.
Was one stock a better investment than the other? Explain your reasoning.
