Questions for Unit 11. A) Provide two examples of functions: (1) as a table of values (with at least 6 input values) and (n) as a graph.B) Use your own words to explain the definition of a function, and how you know that your examples each arefunctions. Be sure to include mathematical vocabulary in your response.2. in a paragraph, explain what the domain and range is for the function, and how you found your answer. f(x) =6x - 25.3. An equation, f, has a domain of all whole numbers and has a range of all real numbers. A) Does the equationrepresent a function? B) Explain why or why not provide examples in either case, (and include your reasoningyou chose this equation for your example.)4. What is the range of the function g(x) = 3x2 - 6x + 3 when the domain is defined as the set of integers, x, such the[0,4]? Show all work5. Part 1. Make sure to show all work. Write both the () recursive formula and the (ii) explicit formula for thesequencesA) (-23,-15,7,1...).B) (5.5.25, 5.50, 5.75...)Part 2- Calculate the 15th term in each of the above sequences, Use the Recursive method for one sequence anExplicit formula for the other sequence. (make sure to label your work & show each step).6. A) After completing #5, please calculate the 20th term for the above sequence, using both methods, then B) Inparagraph, write which formula, recursive or explicit, is easiest for you to use when finding the 20th term in asequence. Explain your reasoning in complete sentences.
