Answer: D) y = 2ˣ
Step-by-step explanation:
The graph is the shape of exponential growth. The only option that satisfies this is D.
A) y = - (1/2)ˣ is a reflection over the x-axis of exponential decay
B) y = (1/2)ˣ is exponential decay because (1/2) < 1
C) y = - 2ˣ is a reflection over the x-axis of exponential growth
D) y = 2ˣ is exponential growth
