Question

If f (x) = StartRoot 4 x + 9 EndRoot + 2, which inequality can be used to find the domain of f(x)?

StartRoot 4 x EndRoot greater-than-or-equal-to 0
4 x + 9 greater-than-or-equal-to 0
4 x greater-than-or-equal-to 0
StartRoot 4 x + 9 EndRoot + 2 greater-than-or-equal-to 0

Answer 1

f (x) = StartRoot 4 x + 9 EndRoot + 2" should be written as Note that √(4x + 9) is a variation of the basic function y = √x, whose domain is [0, ∞ ).
