Answer:

14 feet below. the deck.

Please someone help!! I tried my best to complete this problem but i'm stuck now (also am i even doing it right so far??!);(

Alik [6]

Answer and Step-by-step explanation:

You got everything correct so far except for #4.

4. Yes, it is 1. But it would be in months.

So you would put:

1 month = x

12 months = 1 year.

Since the population increases by 1.5 times a month.

For question number 3.

The equation should be:

$f(x) = 100(1.5)^x$ <- Function

$f(x) = 100(1.5)^{12}$ <- Function when x is 12 months (1 year)

(Put those both the same way I put it.)

It gives you the equation to work with, you just have to plug in the values.

1.5 is in the parenthesis because it needs to be the one that is raised by an exponent.

100 is the initial population, so it stays on the outside.

x is the exponent

F(x) = 2x2 – 15 Find f(-2)

bogdanovich [222]

Wherever you see an x, replace it with -2,
So f(-2) = 2(-2^2) -15
= (2x4)-15
= -7
