f(x)= -2x+1 {-2,0,2,4,6}
If x=-2, then -2(-2)+1 = 5
If x=0, then -2(0)+1 = 1
If x=2, then -2(2)+1 = -3
If x=4, then -2(4)+1 = -7
If x=6, then -2(6)+1 = -11
Answer:
B {5,1,-3,-7,-11}
So the rule with dividing exponents of the same base is to just subtract the exponents. Using this rule, we solve the equation as such:

Next, assuming that you only want positive exponents, to get from a negative exponent to a positive one the rule is
. Using this rule, your final answer is going to be 
48/3 = 16. On the second day she sold 16 notebooks.
16-2(she sold two more each day) = 14
16+2=18
Day 1=14
Day 2=16
Day 3=18
3/2 is an improper fraction.
To make it a mixed number you have to divide 3/2 to see how many times 2 fits into 3. 2 fits into 3 one time. So you write one and next to it, the remainder becomes the numerator and 2 stays in the denominator.
1 1/2 is the mixed number of the fraction.
