You want it to be greater than and equal to 2. A closed circle means to include 2 so you want a closed circle and to the right is to bigger numbers so you want to the right. So the answer is b. Number line with closed circle on 2 and shading to the right.

Answer:
The "formula" for an exponential function is f(x) = a * bˣ where a is the initial value / y-intercept. Therefore, a = 4 so f(x) = 4 * bˣ. To solve for b, we can plug in the values x = 3 and f(x) = 500 which becomes:
500 = 4 * b³
125 = b³
b = 5 so the answer is f(x) = 4 · 5ˣ.
