Question 1205644: Suppose that the function f has a domain of {x ∈ R | x ≥ - 14} and that the function g has a domain of {x ∈ R | x ≤ - 11}. What is the minimum value in the domain of the function (g + f)(x)? Explain.

This is what the number line diagram looks like for each domain.

As the diagram above shows, the two regions overlap for the interval -14+%3C=+x+%3C=+-11
x is some real number between -14 and -11 including both endpoints.

Therefore the domain of (g+f)(x) is -14+%3C=+x+%3C=+-11 which shows that x = -14 is the smallest input allowed for function (g+f)(x).


Answer: -14
