4. Fill in the blanks in the following table to summarize what you have discovered about the end behavior of odd- and even-degree functions. Positive leading coefficient Negative leading coefficient Odd-degree function as x→ ∞, y →→ as x→∞o, y → as x→∞, y →→ as x→∞, y → as x→∞o, y→ Even-degree function as x→∞, y → as x→∞o, y → as x→∞, y → as x→∞o, y → 5. Describe the end behavior of each of the following polynomial functions. A. y=x¹0 +5x²-3 B. y=-2x³5 - 4x + x as x→∞, y →. as x-00, y → as x→∞0, y →

{1,5,10,15} and Y1 = {1,5,10,15,20}. Using the formal definition of a function, determine which of the following subsets of X1 × Y 1 correspond to the functions of X1 → Y 1. Justify your Problem 7. Let X1 = answer by providing reasons why each is or is not a function. 7(a) f = {(1,15),(5,10),(1,5),(10,1),(15,1)} 7(b) f = {(1,20),(5,1),(10,1),(15,5),(1,20)} 7(c) f = {(1,1),(5,1),(10,1)}
