range of f(x)=-2sqrt(x+3)-1

range

f (x) = - 2 x + 3 - 1

f (x) \leq - 1

Interval Notation

(- \infty, - 1]

Solution steps

The range of an radical function of the form

- c a x + b + k

f (x) \leq k

k = - 1

f (x) \leq - 1

in v erse 2 + x + 3

d o main \frac{x ^{2} - 16}{x + 4}

sy mm e t ry y^{2} - 4 y - 6 x - 5 = 0

in v erse f (x) = \frac{3}{x ^{2} + 2 x}

a sy m pt o t es f (x) = \frac{x ^{2} + 9 x + 8}{x - 1}
