Question

Match each function with its domain.

Answer 1

Function: Range:

f(x) = -√x y ≤ 0

p(x) = ∛2-x All real numbers

w(x) = 2 + √x y ≥ 2

r(x) = -2 + √2-x y ≥ -2

k(x) = 2 - √x y ≤ 2

v(x) = √-x y ≥ 0

Answer 2

What you meant was range. The range scales from top to bottom. You can know this by graphing and practicing memorizing these function's domain and range.

Function: Range:

f(x) = -√x y ≤ 0

p(x) = ∛2-x All real numbers

w(x) = 2 + √x y ≥ 2

r(x) = -2 + √2-x y ≥ -2

k(x) = 2 - √x y ≤ 2

v(x) = √-x y ≥ 0
