Hi people,

I really need help finding the range I've never found a set method that always works for example: f(x)= x^2-4/3 for real values of x where x less than or equal to 0.

struggling so any guidance will be appreciated

thanks

Sorry you've not had any responses about this. Are you sure you’ve posted in the right place? Posting in the specific Study Help forum should help get responses.

I'm going to quote in Puddles the Monkey now so she can move your thread to the right place if it's needed. :yy:

The range of the function is the set of possible outputs, given the input.
In your example, can you find the minimum value of the function?
What about a maximum?
By appealing to the continuity of the function, you get that the function then takes every value in between.
