The table is an exponential function, and the equation that represents this function is 
<h3>The equation of the table</h3>
The table is given as:
x F(x)
4 15
5 31
7 127
8 255
Rewrite the table as:
x F(x)
4 16 - 1
5 32 - 1
7 128 - 1
8 256 - 1
Express as a base of 2
x F(x)
4 2⁴ - 1
5 2⁵- 1
7 2⁷ - 1
8 2⁸ - 1
Notice that the function is 1 subtracted from 2 raised to the power of the input.
This is represented as:

Hence, the equation of the table is

Answer:
n=-6
Step-by-step explanation:
2(n+5)=-2
distribute
2(n+5)
2xn 2x5
2n+10
2n+10=-2
subtract 10 from both sides
10-10=0
-2-10=-12
2n=-12
divide each side by 2
2n/2=n
-12/2=-6
n=-6

She can divide the 8 cups by the 1/3 cups
Step-by-step explanation:
The next step will be to divide 8 cups by 1/3 cups
This will be:
= 8÷1/3
=8*3/1-------------dividing by a fraction is the same as multiplying by its reciprocal
= 24
There are 24 1/3cups in 8 cups.

The difference in salary is 36000-28000=8000
The difference in annual increase is 3000-2000=1000
Therefore it takes 8000/1000= 8 years to catch up.
At the end of eight years,
Salary with the first company = 28000+8*3000=52000
Salary with the second company = 36000+8*2000=52000
