Follow the steps for graphing a rational function to graph the function R(x)=(x^2+2x-48)/(x^2-4x-12) If needed, first write the given function as a single rational expression. Then, factor the numerator and denominator of R(x). Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A man is camping on an island 1km from the nearest point on the shoreline. He wants to go to the store which is 4km down the shoreline. The man can paddle his canoe at 7km/h and he can jog at 8km/h. Find x, the horizontal distance along the shore, across from where his island is, that the man should aim to land his canoe in order to reach the store in the least time. Find your answer as a simplified rationalized fraction in the form A/B.

Consider f (x) = 2x* – x3 – 5x2 + 2x + 2. 1. List all possible zeros (candidates) for f(x). 2. Define f (x) in your calculator or desmos. Use the graph to narrow down your candidates. Use synthetic division to reduce f (x) to a quadratic expression. Factor the resulting quadratic expression to find the last two zeros. ZEROS: 3. Express f(x) as a product of linear factors. Don't forget to include the value of a!
