Question

Find the equation of the tangent line to the graph of f(x) = −6x ln(x + 10) at x = 0.

Answer 1

Take the derivative of f(0) in order to find the slope.

Find f(0). This will give you the y-coordinate that corresponds to the zero x coordinate. (x1,y1) = (0, y1)

y-y1=m(x-x1)
where m=slope
