American Highschool Academy Domain Functions Range and Graphs Questions

I need help with my algebra assignment. It includes 10 MULTIPLE CHOICE QUESTIONS and another question that is not multiple choice. The assignment is about domain, functions, range, relations and graphs. Please look at the file below to see if you can do it. It is a GRADED assignment. If you have any questions please write me and i will respond. DO NOT BID ON THIS IF YOU HAVE NO KNOWLEDGE ON FUNCTIONS AND ALGEBRA. Pleaser aim for 100%. THANK YOU

HERE ARE SOME QUESTIONS THAT IS APART OF THE ASSIGNMENT FOR YOU TO LOOK AT TO SEE IF YOU ARE ABLE TO COMPLETE THIS ASSIGNMENT. PLEASE NOTE THAT THERE ARE MORE QUESTIONS, THIS IS JUST A PREVIEW.

Suppose that y = f(x) and it is true that f(3) = 20. Determine whether each is true or false.

• An ordered-pair solution of the function is (3, 20).
• When x is 20, y is 3.
• A possible function if f(x) = x3 – 7.
• A possible function if f(x) = x – 17

Describe a function whose domain is the set of people in your hometown

• If g(x) = x2, which expression is equal to g(x + 1)?
