Question

Consider the following graph of y= f(x): (attached)

Which of the following could be the equation for f(x)?


I. A + Ba^x, with 0 < a <1, B > 0, and A < 0.
II. A + Ba^-x, with a > 1, B < 0, and A < 0.
III. A – a^x+B, with 0 < a < 1, B > 0, and A < 0.

A) I only
B) II only
C) III only
D) II and III only
E) I, II, and III

Answer 1

the third one goes like this: \[III. A – a ^{x+B}, with 0 < a < 1, B > 0, and A < 0.\]

Answer 2

Is it
\[
a^{x+b} \text { or } a^x + b
\]

Answer 3

I am pretty sure it is 3.

Answer 4

3 only?

Answer 5

It was D.

Answer 6

Red is I) \[ -2 + 3 (.5)^x\]
-------------------------------------

Blue is II)\[-2 -3 (2^{-x}) \]
--------------------------------
Green is III)\[-3 - .5^{x+2}\]

Answer 7

I think the answer is D
