Math Problem Statement

g(t) = square root of 3-t - square root of 2+t. Find the domain of the function

Solution

To find the domain of the function g(t)=3t2+tg(t) = \sqrt{3 - t} - \sqrt{2 + t}, we need to determine the values of tt for which the function is defined.

The function involves two square root terms: 3t\sqrt{3 - t} and 2+t\sqrt{2 + t}. For each square root to be defined, the expression inside the square root must be non-negative. Let's analyze each term separately:

  1. Condition for 3t\sqrt{3 - t}:

    3t03 - t \geq 0

    Solving for tt:

    t3t \leq 3

  2. Condition for 2+t\sqrt{2 + t}:

    2+t02 + t \geq 0

    Solving for tt:

    t2t \geq -2

Both conditions must be satisfied simultaneously. Therefore, we need to find the intersection of the intervals:

  • t3t \leq 3
  • t2t \geq -2

The intersection of these intervals is:

2t3-2 \leq t \leq 3

Thus, the domain of the function g(t)g(t) is all tt values in the closed interval [2,3][-2, 3].

Conclusion

The domain of g(t)=3t2+tg(t) = \sqrt{3 - t} - \sqrt{2 + t} is:

[2,3]\boxed{[-2, 3]}

Here are 5 related questions to expand your understanding:

  1. What is the range of the function g(t)=3t2+tg(t) = \sqrt{3 - t} - \sqrt{2 + t} over its domain?
  2. How would the domain change if the function were h(t)=3t+2+th(t) = \sqrt{3 - t} + \sqrt{2 + t}?
  3. How can you graph the function g(t)=3t2+tg(t) = \sqrt{3 - t} - \sqrt{2 + t}?
  4. What are the points where g(t)=0g(t) = 0 within the domain?
  5. How would you find the derivative of g(t)=3t2+tg(t) = \sqrt{3 - t} - \sqrt{2 + t}?

Tip: When determining the domain of functions involving square roots, always set the expression inside the square root greater than or equal to zero to ensure real-valued outputs.
