Question

1.Find the domain and range of (7, - 5), (40, 2) , (-3, 6) (-1,0) 2. Find the domain and range of (2, 4), (4, 2) , (2, 2)(6, 2)

Answer 1

Answer

Question 1

Domain = {7, 40, -3, -1}

Range = {-5, 2, 6, 0}

Question 2

Domain = {2, 4, 6}

Range = {4, 2}

Explanation

The domain of a function refers to the values of the independent variable (x), where the dependent variable [y or f(x)] or the function has a corresponding real value. The domain is simply the values of x for which the output also exists.

The range of a function refers to the region of values where the function can exist. It refers to the values that the dependent variable [y or f(x)] can take on.

Since functions are written in the form, (input, output) or (x, y)

Question 1

Domain = {7, 40, -3, -1}

Range = {-5, 2, 6, 0}

Question 2

Domain = {2, 4, 6}

Range = {4, 2}

Hope this Helps!!!
