Consider the following rational function:
f(x) = 18 (x-1)/(x^2 - 9)
Which of the following are true?
A. The function touches but does not cross the horizontal axisat: x= 1. | |
B. When x is very large and positive, the value of the f(x)approaches to zero. | |
C. The function cuddles up to the vertical lines which passthrough x = - 3 and x =3. | |
D. The function cuts the horizontal axis at x = 3 and x =-3. | |
E. The vertical intercept of the function is (0,2) and thehorizontal intercept is (1, 0). |
