What direction will the parabola open?

$\sf \longrightarrow \: y = - {1x}^{2} + 3x + 9$

The parabola will open in Downward direction.

Remember that when the coefficient of x² is negative the parabola opens in downward direction.
When the coefficient of x² is positive the parabola opens in upward direction.

(-5c - 3) - 2 = -10c + 20 How would I find c?

Ksivusya [100]

(-5c - 3) - 2 = -10c + 20
-5c - 5 = -10c + 20

What is the equation for the kind of reflection?

andre [41]

Answer:

A vertical reflection is given by the equation y=−f(x) y = − f ( x ) and results in the curve being “reflected” across the x-axis. A horizontal reflection is given by the equation y=f(−x) y = f ( − x ) and results in the curve being “reflected” across the y-axis.

Which table shows no correlation?

Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.

Similarly,

6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42
