Find y given x value and f'(x) value
Hello. Is it possible to find y given this...
x=4
f'(x)=3
I don't really see a way to solve it, if possible.
y=mx+b for the tangent line leaves two unknowns...
y=(3)(4)+b
y=12+b
thank you so much.

Re: Find y given x value and f'(x) value
Hi;
I think you need a bit more to find b. There are a lot of linear equations alone that are possible.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
