Answer:

Step-by-step explanation:
Mia used One Third of the felt for her art project. 3/3 would be the whole felt together. Since one part of three sections was used up then this means that 1/3 was used.
We are given: The year of the empire fell = 1610.
We have x as a variable that represents the year after the given year 1610.
According to problem, the year after the year number 1610 will have a number that greater than 1610.
We can make a statement for inequality to be written.
"The year after the 1610 is greater than 1610".
The year after the 1610 is x and we use gerater than symbol >.
So, we can setup an inequality as:
x > 1610 : It can be read as x is greater than 1610.
Easy
remember
x^-m=1/(x^m)
so
f(-1)=4*7^-1=4*(1/(7^1))=4*(1/7)=4/7
f(2)=4*7^2=4*49=196
