What is domain and range
domain is the set of my x values that we input to our function
range is the set of y values that we put into our function

write an explicit arithmetic sequence with the table above then find the 9th term of the sequence
an = a1 + (n - 1)d
an = -7 + (n - 1)3
a9 = -7 + (9-1)3
a9 = 17
