consider the following.
h(x) = x2x − 2
(a) state the domain of the function.
all real numbers except x = 0all real numbers except x = −2 all real numbers except x = −2 and x = 2all real numbers except x = 2all real numbers
(b) identify all intercepts. (enter none in any unused answer blanks.)x-intercept (x, y)=( , )y-intercept (x, y)=( , )
(c) identify any vertical and slant asymptotes. (enter none if there is no asymptote.)vertical asymptote x =slant asymptote y =
(d) plot additional solution points as needed to sketch the graph of the rational function.

use a graphing utility to graph the rational function. give the domain of the function and identify any asymptotes. then zoom out sufficiently far so that the graph appears as a line. identify the line. (enter none in any unused answer blanks.)
f(x) = 2x2 +xx + 1
domain:
all real numbersall real numbers x except x = 0 all real numbers x except x = 1all real numbers x except x = −1all real numbers x except x = −1 and x = 1
