Answer:
Option C!
Step-by-step explanation:
The graph touches the x-axis at -7, since it bounces at that point and change direction. We can know the graph touches and doesn't pass through the x-axis by understanding it is a quadratic function, which always forms a parabola.
x = 1
2x + 1 = -1
2x = -1 - 1
2x = -2
x = -2 ÷ -2
