Solution

domain

2 + 5 x

Solution

x \geq - \frac{2}{5}

+1

Interval Notation

[- \frac{2}{5}, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - \frac{2}{5}

The function domain

x \geq - \frac{2}{5}

Popular Examples

domain of f(x)=((x+9)(x-9))/(x^2+81)domain

f (x) = \frac{( x + 9 ) ( x - 9 )}{x ^{2} + 81}

asymptotes of (-3x^2-12x-9)/(x^2+5x+4)asymptotes

\frac{- 3 x ^{2} - 12 x - 9}{x ^{2} + 5 x + 4}

inverse of f(x)=-2x^3-3 inverse

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

extreme f(x)=x^2-1,-1<= x<= 2 extreme points

f (x) = x^{2} - 1, - 1 \leq x \leq 2

parity 2cos(x)parity

2 cos (x)
