We know that where f is a continuous function with f (2) = - 1 and we also have the plot of f'(x) in the interval [-2,7].
Required to find the equation of the tangent of g(x) at x=2
let's find the derivate of g(x)
At x = 2 we get
from given data we have
From graph of f'(x) we get
Now the tangent equation is ----(1)
where m is slope of the tangent line . That is
(1) -----(2)
At x = 2 we have = y
From (2) we get
