Practice 1. Rakesha claims that the equation f(n) = 5n - 7 is the function notation for the sequence that is represented by the explicit formula q = -2 +5(n − 1). James doesn't understand how this can be the case. a. Help James by listing the steps to write the explicit formula of the given sequence in function notation. Provide a rationale for each step. b. Graph the function. Label the first 5 values of the sequence on the graph. 2. Determine whether each table of values represents a linear function. For those that represent linear functions, write the function. For those that do not, explain why not. C. b. Х f(x) Х f(x) f(x) х 1 11 2 0 14 3 2 16 1 18 -1 4 3 - 4 21 2. 5 23 3 - 7 4. 26 6 29 work
