If f (x) = StartRoot x minus 3 EndRoot, which inequality can be used to find the domain of f(x)? Options Below
A. StartRoot x minus 3 EndRoot greater-than-or-equal-to 0
B. x minus 3 greater-than-or-equal-to 0
C. StartRoot x minus 3 EndRoot less-than-or-equal-to 0
D. x minus 3 less-than-or-equal-to 0

The inequality  can be used to find the domain of

Option B

Step-by-step explanation:

We have , domain is the set of all possible x-values which will make the function "work", and will output real y-values. Basically to find domain of any function means to find range of values of x that will give real values of y.

For the equation   , we know that there's no value  ( iota or complex numbers are there but here we will deal with real numbers ) of negative numbers under square root  

∴ must be greater than or equal to 0.

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
