1. Differentiate each of the following. a) f(x) = x3+5x+2 b) y = c) g(x) 2 + 3x 452 7x + x x 2. Suppose that f(4) = 2, g(4) = 5, /(4) = 6, and g/(4) = -3. Find h/(4). a. h(x)= f(x) g(x) b. h(x) = 7f(x) 2g(x) 3. Find all x-values where the graph of f(x) = x + 3x + x + 3 has a horizontal tangent line. 1.
