domain of f(x)=(sqrt(x+7))/(x-4)

domain

f (x) = \frac{x + 7}{x - 4}

- 7 \leq x < 4 or x > 4

Interval Notation

Solution steps

Find non-negative values for radicals:

x \geq - 7

Find undefined (singularity) points:

x = 4

Combine real regions and undefined points for final function domain

- 7 \leq x < 4 or x > 4

2^{x + 1} - 8

f (x) = \frac{1}{( x ^{2} - 4 )}

f (x) = x^{3} - 12

f (x) = \frac{2 x - 1}{x ^{2} + 9 x}

y = 2^{- x} - 7

What is the domain of f(x)=(sqrt(x+7))/(x-4) ?
The domain of f(x)=(sqrt(x+7))/(x-4) is -7<= x<4\lor x>4
