Question

What is the domain of the square root function graphed below? a)x>= -4b) x>-4c)x>=0d)x>0

Answer 1

Solution:

Given the graph of the function:

$f(x)=\sqrt{x+4}$

to be:

The domain of a function is the set of input values or arguments for which the function is real and defined.

Thus, the domain of the function is

$x\ge-4$
