5.Graphing Technique: Consider the functionR(x)=x2+ x - 6
x2- x - 12
(i)Find the domain(ii) Find the x-intercept(iii) Find the y-intercept
(iv) Find the HorizontalAsymptote(v) Find the Vertical Asymptote
(vi) AnalyzeR'(x)to find the critical value(s)ofR(x) and the partition number(s) ofR'(x). Draw a sign Chart to determine the interval of decrease and the interval of increaseand any extrema.
(vii)AnalyzeR''(x)to find the partition numbers (if any) for R''(x). Draw a sign chart to determine the interval(s) off up-concavity, and down concavity. Locate any inflection point.
(viii)Sketch the graph ofR(x)
