for each of the data sets, a. use technology to create a scatterplot, to determine the best t line, and to compute r. b. indicate whether or not the best t line can be used for predictive purposes for the following x-values. For those for which it can be used, give the predicted value of y: i. x 0 iii. x 12 ii. x 6 iv. x 15 c. Using the best t line, at what x-value would you expect y to be equal to 2?

L11 - 2 Def. The line y = L is called a horizontal asymptote of the graph of f(x)f i How many horizontal asymptotes can a graph have Consider the following functions: x ex. f(x)= x ex. f(x)=1 − e ✻ ✻ ✛ ✲ ✛ ✲ ❄ ❄ −1 ex. f(x)=t n (x) ✻ ✛ ✲ ❄ −1 −1 x→∞m tan (x)=
