Hello there,

Can someone please explain the last step in the screenshot? How did we get 1?

Thanks,
Brindha

Sorry, it’s not clear at all that we’re working with the function f given by the following expression:

f(x) = -\left(x^2\right) + 3x -1

I got this information from this screen in the previous lesson.

Given this, I’ll let you answer your own question. If you’re still having trouble understanding it, do reach out again.

Thank you for the prompt response. I got it now!
