Let $$f\left(x\right)\ =\ \sqrt[]{x\ +\ 1.5}$$ and $$f^{-1}\ \left(x\right)\ =\ x^2\ -1.5$$ , state the domain of f(x). Hint, what number can you put into the radical to = 0?

domain: $$\left[-1.5,\ \infty\right)$$

domain: $$\left(-\infty,\ -1.5\right]\ U\ \left[1.5,\ \infty\right)$$

domain: $$\left(-\infty,\ 1.5\ U\ \left(1.5,\ \infty\right)\right)$$

domain: $$\left[1.5,\ \infty\right)$$
