Start by identifying what type of functions are written into the the function
since there are no variables, we can say that it is a constant piecewise function.
Then it has 3 different constant functions depending on the domain of the function.
for x greater or equal to -5 but smaller than -1 the function is going to be a straight line in y=-5
for x greater or equal to -1 but smaller than 2 the function is going to be a straight line in y=-1
for x greater or equal to 2 but smaller than 5 the function is going to be a straight line in y=2
all of the lines will end with an open circle since it cannot take the final value.
