What are the advantages and disadvantages to representing a function as an equation instead of a graph
Serjik [45]

Answer:

Advantages of representing a function as an equation instead of graph :

  • No chance of misinterpretation of the data as making graph involves more data as compared to data needed to represent function as an equation.
  • Drawing graphs may be inconvenient in case you need to plot fraction and decimal functions.

Disadvantages of representing a function as an equation instead of graph :

  • Visualization is easy in case of graph. Many factors such as maximum, minimum can be easily seen with the help of graph as compared to that of equation of the function.
  • With the help of curve of the graph, we can identify the nature of the function much easily than by the equation of the function.

  4. the rule is not one-to-one

Step-by-step explanation:

Applying the squaring rule to each of the elements of the domain, we get ...

  \begin{array}{cc}\text{Domain}&\text{Range}\\1&1\\-3&9\\-\frac{1}{2}&\frac{1}{4}\\3&9\\2&4\\\frac{1}{4}&\frac{1}{16}\\0.5&\frac{1}{4}\end{array}

__

1. There are 7 different numbers in the Domain list.

2. See above

3. There are 5 different numbers in the Range list.

4. The rule "square me" is not "one-to-one" Two different values in the domain can result in the same value in the range. -3 and 3 both result in 9. -1/2 and 0.5 both result in 1/4.
