Matilda has been studying exponential functions in her algebra class and has started to notice a pattern.

For some exponential functions, when she plugs in larger and larger numbers, she gets larger and larger numbers. For others, she gets smaller and smaller numbers. And for some, plugging in larger and larger numbers actually gets her closer and closer to one number.

Which of the following exponential functions get closer and closer to one value as you plug-in larger and larger values for x?

Select one:

A. f (x) = 0.45 (1.9) x

B. f (x) = -7 (2) x

C. f (x) = (34) x+9

D. f (x) = (65) x-6

Most likely C

Step-by-step explanation:

This is most likely C because it always goes up and although a and c are the only ones with positive equations a makes you multiply by a decimal which can reduce the number so it's most likely C
