Answer
Option B is correct.
The domain of the graphed function is x < 0.
Explanation
The domain of a function is the set of all possible inputs for the function.
It basically means that what are the possible values that x can take on that the function f(x) will still have a rel value.
And from the graph, you can see that this graph represents the function f(x), the red line to be specific.
And the red line starts from the point x= 0 and f(x) = 10; and it is continuous to the left of this point.
So, the domain of the function f(x), which is the range of values that x can take on and the function will still be defined will be all the values of x that are less than 0.
f(x) has a defined value at every value of x less than 0, but, as we can see from the graph (the red line), f(x) stops at x = 0 and f(x) = 10.
Hence, f(x) is undefined at values of x that are greater than 0.
Option B is correct.
The domain of the graphed function is x < 0.
