domain of f(x)=sqrt(1-x)-4

domain

f (x) = 1 - x - 4

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{∣ x - 2 ∣}{2 - x}

f (x) = \frac{5 - 6 x}{2 ( 6 + 5 x )}

f (t) = 4 t^{2} - 6

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

2 x^{3} - 3 x^{2} - 12 x + 8
