range of f(x)=4-2sqrt(2-4x)

range

f (x) = 4 - 2 2 - 4 x

f (x) \leq 4

Interval Notation

(- \infty, 4]

Solution steps

The range of an radical function of the form

- c a x + b + k

f (x) \leq k

k = 4

f (x) \leq 4

f (x) = \frac{1}{5} cos (3 x)

x^{2} + x

2 x + 6

f (x) = lo g_{5} (x + 1)

(0, - 2), (10, - 6)
