# Find an equation of the tangent line to the graph of f ( x ) = 4 ln  x at the point (1,0).Cristovao/Shutterstock.com

To determine

To calculate: The equation of the tangent to the graph of function y=4lnx at the point (1,0).

Explanation

Given information:

The provided function is y=4lnx and the point is (1,0).

Formula used:

Let u be a differentiable function of x then, ddx[lnx]=1x,x>0 and ddx(lnu)=1ududx,u>0

Equation of line is y=mx+b where m is the slope and b=y1mx1 when line passes through (x1,y1)
