- Investigate lim (1 + x) 1/x numerically and graphically. x➔0arrow_forwardI.B. Sketch the graph of a function ? satisfying ALL the given conditions. • The domain of ? is (−∞, ∞) • ?(−4) = −2 • ? intercepts are −2 , 0 , 2 , 4 and 6 • lim?→−4 ?(?) = 0 • lim ?→−2 − ?(?) = +∞ • lim ?→−2 + ?(?) = −∞ • lim?→0 − ?(?) = 0 • lim ?→0 + ?(?) = 3 • lim?→4 ?(?) = −5 • ? is continuous at all except −4 , −2 , 0 and 4arrow_forwardFind limit (a) by investigating values of the function near the point where the limit is taken and (b) by using a graphing calculator to view the function near the point.arrow_forward
- Let G(x) = (x + 6)/(x2 + 4x - 12). a. Make a table of the values of G at x = -5.9, -5.99, -5.999, and so on. Then estimate limx--> -6 G(x). What estimate do you arrive at if you evaluate G at x = -6.1, -6.01, -6.001, .....instead? b. Support your conclusions in part (a) by graphing G and using Zoom and Trace to estimate y-values on the graph as x --> -6arrow_forwardThe graph of h in the figure below has vertical asymptotes at x = -2 and x =3. Find the following limits, if possible (a) lim?→−2-h(?); b) lim?→−2+h(?); (c) lim?→−2h(?); d) lim?→3-h(?); (e) lim?→3+h(?); (f) lim?→3h(?)arrow_forwardUse the graph of the function h(x) given below to answer the questions that follow. (1) Evaluate h(−2) (a) Find lim x → −2- h(x) (b) Find lim x → -2+ h(x) (c) Use your answers from parts (b) and (c) to find lim x→-2 h(x).arrow_forward
- Find a function which has a horizontal asymptote y = 1, and a vertical asymptote x = 1.arrow_forwardFind the lim as h approaches 0 for the given functionarrow_forwardDuring the first four months of employment, the monthly sales S (in thousands of dollars) for a new salesperson depend on the number of hours x of training, as follows: S= S(x)= 9/x+10+x/4, x>=4 (a) Find lim x→4− s(x) (b) Find lim x→10 s(x)arrow_forward
- Sketch a graph of a function satisfying the following properties. 1) lim f(x)= -2 x--> 5 2) f'(5)=DNEarrow_forwardDetermine the following.
