Question

F(x) = x + 5 If you know that the range is {0, 10}, then... The domain must be ??

Answer 1

domain {- 5, 5 }

Explanation:

given values in the range, that is values of y then to find the domain equate f(x) to the given values in the range, that is

x + 5 = 0 ⇒ x = - 5

x + 5 = 10 ⇒ x = 10 - 5 = 5

domain is x ∈ { - 5, 5 }
