OpenStudy (shubhamsrg):
Range is the set of all those real values which function can take for real values of x.
OpenStudy (shubhamsrg):
So in your graph, what is the minimum value (height) the function takes(has) ?
OpenStudy (anonymous):
-3?
OpenStudy (shubhamsrg):
Yep.
And the maximum value ?

none?
OpenStudy (shubhamsrg):
Not none, maximum value is infinity.
OpenStudy (shubhamsrg):
So, your function can have it heights ranging from -3 to infinity, correct ?
OpenStudy (anonymous):
so would it be y>-3?

Almost there
y can also take value -3
so range will be y>= -3
