Find the maximum and minimum values, if any, of the following functions given by
f(x) = – (x – 1)2 + 10
It is given that f (x) = –(x – 1)2 + 10
Now, we can see that (x - 1)2 ≥ 0 for every x ϵ R
⇒ f (x) = –(x – 1)2 + 10 ≤ 10 for every x ϵ R
The minimum value of f is attained when x - 1 = 0
x - 1 = 0
⇒ x = 1
Then, Maximum value of f = f(1) = -(1-1)2 + 10 = 10
Therefore, function f does not have a minimum value.
