What are the domain and range of the function y=2 square root 3x + 4-5?

*A.) X >/= -4/3; Y >/=-5
B.) X >/= 4/3; Y >/= 5
C.) X </= -4/3; Y </= -5
D.) X </= 4/3; Y </= 5

Thank You so much.

  • Algebra -

    for √ to be defined, we need

    3x+4 >= 0
    3x >= -4
    x >= -4/3

    At x = -4/3, y = -5, so for any x >= -4/3, y >= -5

    Looks like (A) all right
