Question

Match each function with its domain.

Answer 1

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

Answer 2

Answer:

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
