As I understand this question you are asked to find the equationOriginally Posted by salted
of the tangent to at the point .
The problem with this is that is not on the curve.
I'm having trouble solving this problem. I have to find the equation of a line tangent to a curve at a specific point. I also have to use a certain technique.
The curve is:
f(x) = x^2+2x+3
The point to be tangent to is:
P = (-1, 6)
I have to use these equations to solve.
m(tan) = lim(x->c) (f(x) - f(c))/(x-c))
y - f(c) = m(tan)(x - c)
I can get to the point where I have (x^2 - 2x) / (x+1). I'm not sure how to proceed. Thanks
