In order to find g(0), we just need to find the value of the function for x = 0.
Looking at the graph, for x = 0 we have y = 7.
Therefore g(0) = 7.
To find the value of x for g(x) = -1, let's look for the value of x where y = -1.
Looking at the graph, for y = -1, we have x = -2.
Therefore g(x) = -1 for x = -2.
