Question 3 (1 point) Which of the following accurately describes the end-behaviour of this function: f(z) = (2 -1)(32 +1)(z - The end-behaviour does not depend on the sign of the leading coefficient. The end-behaviour does not depend on the degree of the polynomial. The leading term is -T' so the end-behaviour is down on the left and up on the right. This is a cubic so the end-behaviour is always up on the left and down on the right. This is a cubic so the end-behaviour is always down on the left and upon the right. This is a cubic with a negative leading coefficient so the end behaviour is up on the left and down on the right. Question 4 (5 points) Sketch the following function using DESMOS: /(x)= -+ 7+2 Analyze the graph by answering the following questions. Correct notation is expected. For infinity, show +inf or -inf, as appropriate. There should be no spaces in your answers.
