What are the domain and range of the function?

f(x)=−3x√

domain: (−∞, 0]

range: (−∞, 0]

domain: [3, ∞)

range: (−∞, ∞)

domain: [0, ∞)

range: [0, ∞)

domain: [0, ∞)

range: (−∞, 0]

  see below

Step-by-step explanation:

The square root function produces a non-negative output for a non-negative input. When its output is negated, it produces a non-positive output for a non-negative input.

The input (domain) is from 0 to infinity: [0, ∞).

The output (range) is from negative infinity to zero: (-∞, 0].
