Question

Find an equation of the tangent line to the graph of f at the given point... f(x) =3x^2 - ln x (1,3)

Answer 1

first, u have to determine the value of slope (m), with m = f '(x)

Answer 2

i meant, after u get f '(x). to find of slope (m) just put x=1 to f '(x), in other words m = f '(1)

Answer 3

and finally, use the formula :
y - y1 = m (x-x1) to get an equation of the tangent line to that curve.
good luck
