Given f"(x) = 8 and f'(x) = 0 and y=3 when x=1, find the equation of y in terms of x.

Hellpppppp

Thanksss :)

Need more information.

I'm inclined to think that the curve is a quadratic y=ax^2+bx+c as that's what most of these questions tend to be.

Really? Hmm but couldn't you use Cx + D for function? Although that doesn't get you anywhere :(

Thanks though. I will quit dwelling on this question then haha

There are infinitely many curves satisfying the conditions you provided, but there is one unique parabola satisfying it, which is why I'm inclined to think it's a parabola.

First integrate f ''(x), so that:



Now, substitute that f '(1)=0, so that: Is this correct in the question?





Integrate again:









So now we get the equation:

So the constant is zero.

So now we get the equation:

it's actually f'(1) = 0, yeah it's not really clear lol
