Explanation:

domain is the valid interval for the x (input) values for the function.

the range is the valid interval for the y (result) values of the function.

so, we have a function definition and a valid domain interval for x. we therefore try the x values and see what result values they create. and that defines the range.

x = -6

y = 4 - -6 = 4 + 6 = +10

c

x = 2

y = 4 - 2 = +2

x = 7

y = 4 - 7 = -3

we have therefore a range of {-3, 2, 10}
