what is the domain of f(x) = square root of 3x + 4 ?

[Jonathan]

Domain is the x value. the x value in this case can truly be anything, as long as 3 times it +4 is greater than or equal to zero. so the domain is "greater than or equal to -4/3" because -4/3 times 3 is -4, +4 is zero. works out perfectly. you can't take a square root of a negative number. the range is greater than or equal to 0.

3X + 4 is in the radical.

please explain how to do this algebra problem thanks

3*x + 4 = 0

x = - 4/3

Domain: ( - 4/3 x < + )
