Question

How do you find the equation of the tangent line of `R(x)= 4x-19` at x=2?

Answer 1

`y=4x-19`

Explanation:

Given -

`R(x)=4x-19`

`y=4x-19`

It is a linear curve. `2` is a point on the curve. If we draw a tangent to that curve at that point, it will co-incide with that linear curve. Hence, equation of the tangent is -

`y=4x-19`
