Answer:
C. The graph would shift five units to the left.
Explanation:
y = x² + 5x - 2
We can write this equation in the form
y = a(x - h)² + k
If you change the value of h, you are translating the parabola horizontally.
If you increase h by five units, the graph shifts five units to the left.
In the figure below, the red parabola represents the original equation.
The blue parabola shows the graph shifting five units to the left
(from x = -2.5 to x = -7.5) when you replace x by x + 5.
