Question

What is the domain and range of the function y equals square root of 4 x plus 12 end root?

Answer 1

Explanation:

The function written symbolically is

f(x) = y = √(4x + 12)

Domain: Since 4x + 12 must be ≥ 0, x must be ≥ -3. [0, -3)

Range: The square root function may be zero or greater: [0, infinity)
