Accepted Solution

A:

Answer:4. The range is -2 ≤ y ≤ 45. The domain is {-2 , -1 , 0 , 3.5 , 4.2}6. The relation is not a functionStep-by-step explanation:* Lets explain how to solve the problem# Question 4:- The range of the function is the values of all y (output) which is corresponding to the values of all x (input)- The figure is a stare, the values of x is from -4 to 4∴ The domain is -4 ≤ x ≤ 4- The corresponding values of y are from -2 to 4∴The range is -2 ≤ y ≤ 4# Question 5:- The table represent a relation between x and y- x is the input of the relation- y is the output of the relation∵ The input of the relation is called the domain of it∴ The domain of the relation is all values of x in the table- the values of x are -2 , -1 , 0 , 3.5 , 4.2∴ The domain is {-2 , -1 , 0 , 3.5 , 4.2}# Question 6:- The relation can be a function if each ordered pair has a unique value of x (input)- That means every x (input) has only one y (output)- Ex : The relation {(a , b) , (c , d) , (a , f)} is not a function because the input a has two output b and f∵ The relation is {(-4 , 0) , (-3 , 0) , (-2 , 1) , (1 , -2) , (-3 , 4)}∵ The x = -3 has two values of y 0 and 4∴ The relation is not a function
