Ответ:
y = (10/9)x^2
Step-by-step explanation:
The vertex is at (0, 0), so the parent function is y=x^2 with no vertical or horizontal translation. A vertical scale factor can be used to make the graph go through the given points.
For x=3, the parent function gives ...
y = 3^2 = 9
The actual value you want is 10, so is a factor of (10/9) times the value you have. That is ...
10 = (10/9)×9
Applying this scale factor to the parent function gives you ...
y = (10/9)x^2
