domain of f(x)=sqrt(x+2)*(x^2)/(x-4)

domain

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

- 2 \leq x < 4 or x > 4

Interval Notation

[- 2, 4) \cup (4, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 2

Find undefined (singularity) points:

x = 4

Combine real regions and undefined points for final function domain

- 2 \leq x < 4 or x > 4

What is the domain of f(x)=sqrt(x+2)*(x^2)/(x-4) ?
The domain of f(x)=sqrt(x+2)*(x^2)/(x-4) is -2<= x<4\lor x>4
