domain of 4-x,x<1,8x-5,x>= 1

domain

4 - x, x < 1, 8 x - 5, x \geq 1

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Domain of

{4 - x : x < 1} : x < 1

Domain of

{8 x - 5 : x \geq 1} : x \geq 1

Combine domains of all the pieces:

x < 1 or x \geq 1

- \infty < x < \infty

f (x) = ∣ x - 3 ∣ - 2

f (x) = 2^{x + 2} - 4

f (x) = ln (7 - 2 x)

f (x) = ∣ x - 3 ∣ + 2

f (x) = ∣ x - 3 ∣ + 1
