domain

f (x) = 15 - 3 x

x \leq 5

Interval Notation

(- \infty, 5]

Solution steps

Find non-negative values for radicals:

x \leq 5

The function domain

x \leq 5

l in e (- 3, - 5), (- 1, 0)

p a r i t y f (x) = 2 x^{2} + 3 x - 1

d o main f (x) = \frac{1}{6} x

s l o p e y = x + 6

cr i t i c a l f (x) = \frac{1}{2} x^{2} + 8 x + 5
