Fiona started her study of bacteria growth with 1,000 bacteria in a petri dish. after 1 hour, the count was increased to 1,800. after 2 hours, the count was 3,240. after the third hour showed a count of 5,832, fiona wrote an equation to represent the exponential growth of the bacteria. what exponential growth function did fiona write?
f(x) = ( )x

An exponential growth function is given by:

.....[1]where a is the initial value and b is the growth factor.

As per the given statement: Fiona started her study of bacteria growth with 1,000 bacteria in a petri dish.

⇒Initial value(a) = 1000

Also, it is given that:  After 1 hour, the count was increased to 1,800. After 2 hours, the count was 3,240. also, After the third hour showed a count of 5,832,

Let x represents the time in hour and y represents thee count of bacteria.

Then; from the statement we have;

and (2, 3240)

Now, using these point we find the exponential growth function;

Substitute these in [1] we get;

        .....[2]

        ....[3]

Divide equation [3] by [2] we get;

Simplify:

Now, substitute the value of a =1000 and b = 1.8 in [1] we get;

Therefore, the exponential growth function is,

I just finished doing this

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
