I need help solving all the questions. 1. Rakesha claims that the equation f(n) 5 5n 2 7 is the function notation for the sequence that is
represented by the explicit formula an 5 22 1 5(n 2 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 fi rst 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.
