Question

Help me with 1 and 2

Answer 1

Answer:

• 2)A function can be represented verbally. For example, the circumference of a square is four times one of its sides.
• A function can be represented algebraically. For example,3x+6.
• A function can be represented numerically.
• A function can be represented graphically.

3)Comparing two mathematical functions and studying the properties of one function are two different problems. Most of the properties you listed are properties a function has, rather than what you would use to compare two functions. Yes you can compare two functions by stating that they have different domains/ranges, whether one is injective and another is not, but these comparisons aren’t really that interesting (rather, we are more interested in whether a function has certain properties).
