domain of f(x)=(2x)/(sqrt(10-x))

domain

f (x) = \frac{2 x}{10 - x}

x < 10

Interval Notation

(- \infty, 10)

Solution steps

Find non-negative values for radicals:

x \leq 10

Find undefined (singularity) points:

x = 10

Combine real regions and undefined points for final function domain

x < 10

h (x) = \frac{x ^{2} - 9}{x - 2}

y = e^{3} (e - 2 a)

- 3 x + 2 - 6

f (x) = \frac{3 - 7 x}{8 x}

f (x) = 3 (x - 2)^{2} - 9
