Hey I'd really appreciate help with this question please I really can't remember how to do it! Is f(x)=9-(x-2)^2 write down the maximum value of f(x) please leave working out too Thankyou!!!

Why would I leave working out? Have a go at it yourself.
It's a quadratic so it's when (x−2)2=0 so you're not subtracting anything. You can sketch the thing anyway and see it.
Otherwise differentiate it, solve it for x, and plug the solution back through the function.
