Chapter 2.1, Problem 52E
To determine

Find the domain of the function f(x)=x+94

Expert Solution

Answer to Problem 52E

The domain of the function f(x)=x+94 is [9,)

Explanation of Solution

Given information: Consider the function f(x)=x+94

Calculation:

We can’t take the square root of a negative number, so we must have f(x)0

  x+90x9

Hence the given function is defined for all the values of x in the set of real numbers except of the values less than -9.

Thus, the domain of the function f(x)=x+94 is [9,)
