1.) y = 1/2x^2 - x 2.) y = x^2 + 4x 3.) y = x^-2 4.) y = 2x - x^2 I'm having difficulty to find the critical points of these. Usually they're two. Help :(
Here's the third one:
P.S cloud you guys also solve it. Maxima and minima. Many thanks in advance!
Hallo guest, here the first one.
Here's the second one:
Here's the last one
I have a question. What do you mean?
y=x^-2 or y=x^2-2
Thank you. You've really helped me alot. It's x raised to negative 2.
Very nice, Omi67......!!!!
Hallo CPhill,
thank you. I am living in Germany. Sometimes I do not understand the questions. I use a translation programme. I cannot speak so well in English. I am an old woman. I have learnt at school little English.
