Consider the following function f(x) = (x +3x+1)e] Find the x-coordinate of the point where the tangent line to the graphe of f is horizontal. Answer: FORMATTING: If there is more than one point, separate these x values with a semi-colon.This question is to emphasize how our differentiation rules can be used even when it doesn't look like you know enough about a function. (This is a handy trick to use when your formula is very long to write out) 1+f(x) Set h (I) = , where f and g are differentiable functions that satisfy g (I) f(1) = 1, f' (1) = 5, g(1) = 4, and g' (1) = 2. Write down a formula for h(x) on paper. Using this and the information above, find the value of h (1). Answer: h (1) =
