range of f(x)=-sqrt(x)-3

range

f (x) = - x - 3

f (x) \leq - 3

Interval Notation

(- \infty, - 3]

Solution steps

The range of an radical function of the form

- c a x + b + k

f (x) \leq k

k = - 3

f (x) \leq - 3

f (x) = x^{2} + 2 x + 1

f (x) = \frac{( 5 x - 3 )}{2 x + 5}

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

f (x) = (x + 2)^{2} (x + 1)

f (x) = \frac{1 + 9 x}{5 - 4 x}
