To determine

Find the domain of the function h(x)=2x5

Expert Solution

Answer to Problem 55E

The domain of the function h(x)=2x5 is [52,)

Explanation of Solution

Given information: Consider the function h(x)=2x5

Calculation:

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

  2x50x52

Hence the given function is defined for all the values of x in the set of real numbers except of the values less than to 52 .

Thus, the domain of the function h(x)=2x5 is [52,)
