# Find the maximum and minimum values, if any, of the following functions given by f (x) = – (x – 1) ^2 + 10

1. Find the maximum and minimum values, if any, of the following functions
given by

(iii) $f (x) = - (x -1) ^2 + 10$

Given function is,
$f (x) = - (x -1) ^2 + 10$
$-(x-1)^2 \leq 0\\ -(x-1)^2+10\leq 10$    for every $x \ \epsilon \ R$
Hence, maximum value occurs when
$(x-1)=0\\ x = 1$
Hence, maximum value of function $f (x) = - (x -1) ^2 + 10$  occurs at  x = 1
and the maximum value is
$f(1) = -(1-1)^2+10=10 \\$

and it is clear that there is no minimum value of  $f (x) = 9x^2+12x+2$
