tangent of f(x)=(1+2x)/(1-2x),(1,-3)

tangent of

f (x) = \frac{1 + 2 x}{1 - 2 x}, (1, - 3)

y = 4 x - 7

Solution steps

Find the slope of

f (x) = \frac{1 + 2 x}{1 - 2 x} : \frac{df ( x )}{d x} = \frac{4}{( 1 - 2 x ) ^{2}}

Find the line with slope m=

4

and passing through

(1, - 3) : y = 4 x - 7

y = 4 x - 7
