Question

Which model does the graph represent?

Which model does the graph represent?

A.
A

B.
B

C.
C

D.
D

Answer 1

C

Explanation:

A models an exponentially increasing function.

B models an exponentially decreasing function.

C models a "bell" curve, similar to the one shown.

D models a "logistic" function, an s-shaped curve that smoothly transitions between two horizontal asymptotes.

Answer 2

Answer: The correct one is C

Explanation:

The gaussian curve ( the one you can see in the graph) is described by C.

You can see that A is an exponential function that only will grow as t grows.

B will decrease asymptotically to zero as t grows, the same with D, as t grows, D only can decrease.

but for C you will have the maximum when x = b, and a exponential decrease when x decrease or when x increase which forms the bell that you see in the graph.
