Can someone explain how I can find the range of a function with a prescribed domain.
E.X
f(x) = 2x^2 + 4 for –3 < x < 5. What is the range of f?
f(x) = 1/x for -2 < x < 3 What is the range of f?
Thanks in advance =]!

Hello Ferken,
The function, is an upward parabola whose minimum value is 4 when x = 0.
Here, f(0) = 4
f(-3) = 22
and f(5) = 54
so, Range
Please see the attached graph for more clarification.
Now, do the second question in the same way.
Did you get it now ???
