PLEASE HELP ME! THANK YOU! :)

QveST [7]

All we need to do is to divide August and September rainfall measurements into two equal halves and then substract 0.6 from one of them and add 0.6 to the other one.

6.2 ÷ 2 = 3.1
3.1 - 0.6 = 2.5
3.1 + 0.6 = 3.7

It's said that in August there was 0.6 inch more rainfall, so the bigger value (3.7 inches) is for August and the smaller value (2.5 inches) is for September.

If f(x)f(x) is an exponential function where f(-1)=5f(−1)=5 and f(7)=32f(7)=32, then find the value of f(4)f(4), to the nearest

Whitepunk [10]

Using an exponential function, it is found that the value of the function when x = 4 is of f(4) = 15.95.

<h3>What is an exponential function?</h3>

It is modeled by:

$y = ab^x$

In which:

a is the initial value.

b is the rate of change, as a decimal.

In this problem, we have that f(-1)=5, hence:

$5 = ab^{-1}$

$\frac{a}{b} = 5$

a = 5b

We also have that f(7)=32, hence:

$32 = ab^7$

Since a = 5b:

$5b^8 = 32$

$b = \sqrt[8]{\frac{32}{5}}$

b = 1.2612.

a = 5b = 5 x 1.2612 = 6.306.

Hence the function is given by:

$y = 6.306(1.2612)^x$

Then, when x = 4, we have that:

$y = 6.306(1.2612)^4 = 15.95$
