you will need the 1st and 2nd derivatives 1st derivative = 0 gives the stationary points 2nd derivative is used to determine the nature of the stationary points

it thats to difficult, just find a graphing package and graph the curve like geogebra http://www.geogebra.org/cms/

No calculus experience? Look like you have to use a calculator or a graphing program like @campbell_st said.

um can you just show me the steps or something....I have a textbook and the instructions aren't the issue its my ability to apply it to this problem

ok... here is the easiest solution, use the table of values below,..... dw:1352186589941:dw substitute each x value into the graph... the largest positive y value will be the relative maximum and the largest negative y value will be the relative minimum. when you have done that, you'll find ordered pairs that match your choices...
