domain of f(x)= 4/(x+4)+sqrt(x)+1

domain

f (x) = \frac{4}{x + 4} + x + 1

x \geq 0

Interval Notation

[0, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 0

Find undefined (singularity) points:

x = - 4

Combine real regions and undefined points for final function domain

x \geq 0

y = \frac{1}{5} x + \frac{4}{5}

f (x) = 7 - x

f (x) = s (x) = 3 cos (120 π x)

f (x) = 2.2 + 2.2 x - 0.6 x^{2}

f (x) = - 16 t^{2} + 40 t + 3
