1. Lat f() = 5x + dr' + 15x + 1; (a) Find the intervals where is increasing and decreasing Identify the relative extrem (b) Find the intervals where is concave up and down and identify any inflection points. (c) Evaluate lim (1) and lim (2) (d) Sloetch a graph of 2. Let f'(x) = 21. Assume the domain of is (-.-1)0(-1,00). Note you are being given the derivative off but asked questions about itself. (n) Find the intervals where is increasing and decreasing Identify the relative extrema (b) Find the intervals where is concave up and down and Identify any inflection points (c) Assume lim(a) = lime 1/600 and f(-4) - 1 and f(1) = 2.
