domain of f(x)=-2sqrt(1-x)

domain

f (x) = - 2 1 - x

x \leq 1

Interval Notation

(- \infty, 1]

Solution steps

Find non-negative values for radicals:

x \leq 1

The function domain

x \leq 1

+ (- \frac{1}{6}) x^{2} + 200 x

y = \frac{1}{x} + 3

6 x^{4} - x^{3} - 25 x^{2} + 4 x + 4

f (x) = - 2 (x + 1)^{3} - 3

\frac{9 + 3 ( 27 + 4 y ^{2} )}{2 y}

What is the domain of f(x)=-2sqrt(1-x) ?
