domain of sqrt(1-a)+sqrt(1-a^2),(-1<a<1)

domain

1 - a + 1 - a^{2}, (- 1 < a < 1)

- 1 < a < 1

Interval Notation

(- 1, 1)

Solution steps

Set the domain to the given interval

- 1 < a < 1

Find non-negative values for radicals:

- 1 \leq a \leq 1

Join real regions with the domain:

- 1 \leq a \leq 1 and - 1 < a < 1

- 1 < a < 1

f (x) = 9 x^{2} + 8 x - 12

f (x) = 5 x^{2} + 56 x + 45

p (t) = \frac{101}{1 + 40 e _{0.5} t}

f (a) = a^{3} - a^{2} - 2 a + 3

g (u) = (1 + u^{2})^{5} \cdot (4 - 7 u^{2})^{8}
