1. stauionary points on the curve y = x^2 e ^ -x
y' = xe^-x

so x=0 and x=2

y"= 2x(e^-x) + - e^-x(2)

at 0,0 max point

at 2,0.541 min point

i have done the working out for finding min and max just cba typing it out, just simplified everything down for here

Don't use decimals. Leave it in exact form.

x=2, y = 2^2(e^-2) = 0.5414311329 there is no exact form

is the exact form.... you've literally written it out...

..........

Yes there is. You literally wrote it out right after the equals sign on y.
