Please provide clear explanation. Thank you.

If is a function satisfying 8(3) =8'(3) =-2 , and h(x) =tan [g(x)] , then what is h'(3) .V Enter your answer as a decimal number, rounded to two decimal points.Find the equation of the line that is tangent to the curve y = x at the point (2, 4) Show and explain your work. Hint: Use logarithmic and implicit differentiation. That is, apply In() to both sides of the equation, and then differentiate with respect to X
