Question

Equal functions are two functions that have _____ domains, and, for each value in the domain set, _____ range values respectively. same, different different, equal different, different same, equal

Answer 1

1. Same

2. Same

Explanation:

If the following two properties apply to any of the two functions, then they will be called equal:

1. If the domains of two different functions are same then they are said to be equal functions; and

2. If the range of two functions are same, then they are equal functions.

Therefore, for two functions to be equal, they must have same domain and range.

Answer 2

Answer is same, same.

Two functions are said to be equal or identical if-

(1) They have same domain.

(2) They have same Range and

(3) For same value of x (independent variable), we get same value of y (dependent variable).
