Let Y = 1 + 3 cos 2x

Now We Know that Cos Function lies
between -1 to 1

So putting These Value We get

Maximum Value = 1 + 3*1 = 4
Minimum Value = 1 + 3*(-1)= -2

So the range of f(x) is [-2,4].

As we know that constant function y=f(x)=C is elsewhere continious but if we write this function as f(x)=Cx^0 then f(0)=C0^0 where 0^0 is indeterminate Then it f is not continues elsewhere. Please share some suggestions so that i clear my wrong concept if exist

Bro,I was also asking this same question in 11th class to my maths teacher- he explain it as " if you want to understand this continuation for this graph then you have to know about left hand and right hand limit approach for a function in its domain (take any point you want ) then in order to solve this indeterminate limit you solve it by log method( log property also used) , then by solving this you get the same constant value as earlier you want to approach, so now it's mathematically proved as we get the same constant each and every input value.
