De figuur is de grafiek van de functie f : y = a x2 + b x + c. Hieruit volgt dat |
A. a > 0 en c > 0 |
|---|---|
| B. a > 0 en c < 0 | |
| C. a < 0 en c > 0 | |
| D. a < 0 en c < 0 | |
| E. a = 0 of c = 0 |

The figure is the graph of the function f : y = a x2 + b x + c. We can conclude that |
A. a >0 en c >0 |
|---|---|
| B. a >0 and c <0 | |
| C. a <0 and c >0 | |
| D. a <0 and c <0 | |
| E. a = 0 or c = 0 |
