Answer 1

For this case, what you should see is where the graph cuts the x-axis.
 Notice that the graph cuts to the x axis in three different points.
 Then the value of x that is in the domain of the function in this case is:
 x = 1
 For this value of x the function is zero.
 Answer:
 x = 1

Answer 2

Answer:
x = 1

Explanation:
We are looking for f(x) = 0, this means that we are looking for the x-value that has a y-value = 0. The points having y=0 are located directly on the x-axis.

Taking a look at the graph, we can find that we have 3 points with a y-0 value, these points are (-2.5,0) , (-0.5,0) and (1,0)
This means that the values of x having f(x) = 0 are -2.5, -0.5 and 1.
Checking the choices, we would find that we have a choice x=1 which would be the correct one.

Hope this helps :)
