Is this problem correct
F (x)= x² - 3x + 1=
2x+3+1=
2(1)+3+1=
2+3+1= 6?

Or solve it and show me where I went wrong... Thanks.

What exactly are you trying to do?

anonymous · Answer

how did you get from step 1 to step 2? It looks like a derivative, but then the 1 shouldn't be there.

anonymous · Answer

yes @alffer1  that's what it is but I really don't understand this subject... so I;m just guessing

anonymous · Answer

can anyone explain?

anonymous · Answer

You're on the right track, but the derivative of 1 is 0. The derivative of any constant is zero.

anonymous · Answer

The rest is perfectly right. So the answer is 5.

anonymous · Answer

You used the power rule to find the derivatives of the others, right?

anonymous · Answer

:O :) thanks ...so happy I wasn't completely lost thanks @alffer1
