At witch value in the domain does f(x)=0?

Step-by-step explanation:

f(x)=0

Domain are the set of x values

f(x)=0 , we find all the x values where y =0

At x intercepts y is always 0

so we find all the x intercepts.

x intercepts are the points where the graph crosses x axis

In the graph we can see that the graph crosses x axis at

-2.5 , -0.75 and 1

-2.5 , -0.75 and 1 are the domain where f(x)=0

the expected value of the random variable : 0, 1 and 2

might be the correct answer will be question number 2
