domain of f(x)=sqrt(x)+3

domain

f (x) = x + 3

x \geq 0

Interval Notation

[0, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 0

The function domain

x \geq 0

y = - 3 x^{2} + 48 x - 195

f (x) = 7 - x^{2}

f (x) = \frac{3}{5 x ^{5}}

f (x) = \frac{9 x - 9}{2 x + 7}

y = \frac{3 x}{x ^{2} + 25}
