MATH 205 Study Guide - Quiz Guide: Imaginary Number, Piecewise, Farad

Determine the end behavior, plot the y-intercept, find and plot all real zeros, and plot at least one test value between each inte f(x)-2x3+x-13x+6 Choose the correct end behavior for f(x). O The ends of the graph will extend in the same direction, because the degree of the polynomial is even. O The ends of the graph will extend in opposite directions, because the degree of the polynomial is odc. The ends of the graph will extend in the same direction, because the degree of the polynomial is odo O The ends of the graph will extend in opposite directions, because the degree of the polynomial is even. The y-intercept is(Type an integer or a simplified fraction.) The zeros of the poljynomial are x (Simplify your answer.

(x, y)一 eBook The following guidelines for your graphing calculator may be helpful to find the x-intercept For the TT-83/84: Input the linear equation in the Y- graph menu. After graphing the linear equation, press 2nd CALC and select 2:zero, then press ENTER. At the lower part of the screen you will see "left bound?" and a blinking cursor on the graph of the line. Move this cursor to the left of the x-intercept, hit ENTER. Now it says "right bound?" Move the cunsor to the right of the x-intercept, hit ENTER. Now it says "guess?" Move your cursor to the left somewhere in between the left and right bound near the x-intercept. Hit ENTER. At the bottom of your screen it wii display the coordinates of the x-intercept or the "zero" to the y-value (Note: With linear/straight line functions the zero is not really a "guess," but is boundare, wah ether types of functions (more than one ritercept), they may be rational numbers so-guess,s more approprate to give the correct limits to find. very close For the T1-89: Input the linear equation in the Y- graph menu. When viewing the graph of the inear equation, press FS and select 2 zero then press ENTER. At the lower part of the screen will see "lower bound? and a blinking cursor on the graph of the ine. Move this cursor to an x-value less than the x-interoept, ht ENTER. Now it says "upper greater than the x-intercept·NE ENTER. At the bottom of your screen " will display the coordinates of the x-intercept or the "zero" to the r.value. Book
