Step-by-step explanation:

Suppose you are standing on a street corner. Suppose that you are counting cars. You notice that there are only black ones and white ones. For every 3 black cars there are 4 white ones. Beginning ratios always look something like this.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
