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

a.) StartRoot 4 x EndRoot greater-than-or-equal-to 0
b.) 4 x + 9 greater-than-or-equal-to 0
c.) 4 x greater-than-or-equal-to 0
d.) StartRoot 4 x + 9 EndRoot + 2 greater-than-or-equal-to 0

The answer is actually b. Just took this quiz :)

Step-by-step explanation:

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
