domain of f(x)=arccos(e^{3x})

domain

f (x) = arccos (e^{3 x})

x \leq 0

Interval Notation

(- \infty, 0]

Solution steps

Find known functions domain restrictions:

x \leq 0

The function domain

x \leq 0

f (x) = \frac{1}{x ^{3} + 1}

f (x) = 6 t^{2} + 500 t + 8000

\frac{x + 7}{x ^{2} + 2 x}

y = \frac{1}{sec ^{2} ( x )} + \frac{1}{csc ^{2} ( x )}

\frac{4 ln ( x )}{11 x ^{2}}
