domain of f(x)=sqrt(t+15)

domain

f (x) = t + 15

t \geq - 15

Interval Notation

[- 15, \infty)

Solution steps

Find non-negative values for radicals:

t \geq - 15

The function domain

t \geq - 15

+ 117 x^{4} - 78 x^{3}

\frac{2 x}{x - 1}

f (x) = \frac{x + 3}{2 x ^{2} + 5 x + 2}

\frac{( x + 1 )}{( x ^{2} - 13 x + 42 ) ^{\frac{1}{2}}}

f (θ) = 1 - cos (θ)
