Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=3100(0.365)^x

Growth

% increase

Decrease of 63.5%.

Step-by-step explanation:

Exponential function:

An exponential function has the following format:

In which y(0) is the initial value and r is the rate of change, as a decimal. If r is positive, it is a increase. If it is negative, it is a decrease.

In this question:

We have that:

So

So a decrease of 63.5%.

answer: i believe its b. if you sound out the sentences that sounds wrong.

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
