The functions below represent exponential growth or decay. What is the initial quantity? What is the growth rate? Is this growth or decay, and how do you know? Make a rough sketch of the graph of the function and write a story problem to go with each equation.
a. = 8(1.23)
b. = 3.1(0.78)
c. = 3.1(0.78)
d. = ( 2 3 )
e. = 1 4 ( 3 2 )

the 3rd option is right

step-by-step explanation:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

i think the answer is b.

step-by-step explanation:

not 100% sure though.
