f(x)=∣x−1∣f(x) = |x - 1| , f:R+→Rf: R^+ \rightarrow R , g(x)=exg(x) = e^x , g:[−1,∞)→Rg: [-1, \infty) \rightarrow R . If the function f∘g(x)f \circ g(x) is defined, then its domain and range respectively are: (a) (0,∞)(0, \infty) and [0,∞)[0, \infty) (b) [−1,∞)[-1, \infty) and [0,∞)[0, \infty) (c) [−1,∞)[-1, \infty) and [1−1e,∞)\left[1 - \frac{1}{e}, \infty\right) (d) [−1,∞)[-1, \infty) and [1e−1,∞)\left[\frac{1}{e} - 1, \infty\right)
