Answer:
y = -3 + 6ˣ
Explanation:
-3 is the lowest it goes, and the more you increase the base, the more it its stretch will become. Now, although it passes through -2, we are not dealing with y-intercept here because this is NOT a linear function. This is called a horizontal asymptote. This is an exponential function, from the parent function of y = abˣ, if I can recall correctly. Anyway, you understand?
