f (x) = 9e x2 − 10x, 0 ≤ x ≤ 6

a) Find the smallest value of f (x) on the given interval.

b) Find the largest value of f (x) on the given interval.

Find the largest value of f (x) on the given interval.

#1  It is very hard to read the definition of f(x). In today's world, it's really not optional to learn a little LaTeX. Just a little. I usually just code it by hand. There are fancier ways.
Is it \(\displaystyle f(x) = 9e^{x^{2}}  10x\)? Coded as [ t e x ] f ( x ) = 9 e ^ { x ^ { 2 } }  1 0 x [ / t e x ]
#2  What's the idea concerning how to use the 1st Derivative to accomplish what you have been asked to do?
#3  The 1st Derivative knows nothing of endpoints. Check those separately before you think you are done.
