Which is an exponential growth function? A) f(x) = 6(0.25)x
B) f(x) = 0.25(5.25)x
C) f(x) = –4.25x
D) f(x) = (–1.25)x

f(x) = 0.25(5.25)ˣ

Step-by-step explanation:

In order to show exponential growth, the numbers must be positive and the base of the exponent must be larger than 1.

Think of it as a percentage.  The base of the exponent will be the percentage of the original amount taken each time; if it is less than 1.00 then it would shrink.  Larger than 1.00 will grow.  The only one with positive numbers and a growth factor of greater than 1 is f(x) = 0.25(5.25)ˣ.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
