Identify all values of a that will make the function open upward.
Identify all values of c that will make the function have a y-intercept above the origin.
Match each statment on the left with the value on the right that would make it true:
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
The graph will pass through the origin (0,0) | arrow_right_alt | c = 7 |
The graph's vertex will be on the y-axis | arrow_right_alt | a = 4 |
The graph will open downward | arrow_right_alt | c < 0 |
The graph's y-intercept will be below the origin | arrow_right_alt | b = 0 |
The graph will open upward | arrow_right_alt | c = 0 |
The graph will have a y-intercept at (0,7) | arrow_right_alt | a = -0.5 |
