1. Give an example of a function, f(x), with a domain of (0,5] and a range of [0,∞)
* reference1

2. If f(t) = 2t – t2, what is (f(t + h) – f(t)) / h?

3. If F = { (1,2), (3, 5), (4,7)} and G = { (1,4), (3,0), and (5, 2)}, what is F + G? What is F/G (using arithmetic function)?

1. \( f(x)=\sqrt[2]{\frac{5}{x}-1} \)
2. -2t-h+2
3. (1) F + G
F + G = {(1,6),(3,5)}
3. (2) F/G
F/G = {(1,1/2)}
