domain of y=x+8/x ,x>0

domain

y = x + \frac{8}{x}, x > 0

x > 0

Interval Notation

(0, \infty)

Solution steps

Set the domain to the given interval

x > 0

Find undefined (singularity) points:

No real undefined points

Join undefined points with the domain:

(x < 0 or x > 0) and x > 0

x > 0

f (x) = \frac{( x ^{2} + 9 )}{x ^{2} - 15 + 192}

y = \frac{1}{11 + x}

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

f (x) = - 14 + 7 x + 18

f (x) = \frac{5 - x}{x + 1}
