Identify the exponential function graphed in the picture.
the picture and the answer choices are provided.

The answer is D i think because the line has an asymptote of x = 2 and it is the only option with + 2 in the equation

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
