Math 95 – Froemke – Spring 2011 – Project 1 – Due Saturday, April 23rd
1) Find and copy down a definition of ‘function’. Cite your source! Then explain that definition in your own words. Make sure you explain all of the important parts.
2) Describe what domain and range mean (in terms of functions) in your own words. A specific example might help.
3) The long side of a right triangle is two feet shorter than the hypotenuse, and the short side of the right triangle is four feet shorter than the hypotenuse. Find the lengths of the sides of this triangle. Show your work!
4) Consider the function g(t) = (3t – 2) / (3t2 + 10t – 8). Find the value(s) of t which make g(t) undefined.
5) Simplify the following as much as possible. Show all your steps!
4 / (t+2) + 7 / (t+2)2
