Domain
Steps:
- Go to mode and press 7 for table mode.
- Copy question after f(x)=
- Start with 1 less than lowest value and end with 1 more than largest one.
- Put steps as required. generally 1 but not always.
- After putting steps press '=' than you will get a table having values of x and f(x). The option excluding the value of x which gives error on the value of f(x) and including all the values of x that are giving certain values of f(x) will be the correct answer.
- watch above video for detail explanation and for example.
Range
Steps:
- Go to mode and press 7 for table mode similar as domain.
- Copy question after f(x)=
- Start and end values for algebraic expression usually should be -5 to 5. You should vary these values as required. And for trigonometric expressions start and end values should be 0 to 2pie or 0 to 360 degree.
- Put steps as needed. for algebraic usually 1 and for trigonometric expression usually 45 or 30 degree, or pie/4 or pie/6.
- Then observe the table created. the option which includes all the values on f(x) and not including more extras will be the correct answer.
