Your answer What is the value of x, you didn't specify

It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable. ... A variable need not be “x,” but might be “y,” "w," or any other letter, name, or symbol.

If f(x)=square root 4x+9+2, which inequality can be used to find the domain of f(x)?
jenyasd209 [6]

we have

f(x)=\sqrt{4x+9} +2

we know that

The radicand must be greater than or equal to zero

so

4x+9 \geq0 \\ 4x\geq -9 \\x\geq -\frac{9}{4} \\ x\geq -2.25

the domain is is the interval--------> [-2.25,∞)

therefore

<u>the answer is</u>

4x+9 \geq0
