Question 6 Use linear approximation, i.e. the tangent line, to approximate v64.4 as follows: Let f(I) = VT. The equation of the tangent line to f(x) at I = 64 can be written in the form y = mr + b where m is: and where b is: Using this, we find our approximation for V 64.4 is Submit Question 11:38 PM ENG ~ 12/13/2022 9
