Looking at the graph, how can I answer the questions A, b, c and d?

QUESTION 3 4 6 8 -10 -15 20 A) For each of these points f (I) = B) These types of points are called horizontal asymptotes vertical asymptotes y-intercepts Or-intercepts The points where f(I) - 0 go by several names. Sometimes they are called I-intercepts, sometimes boundary points, sometimes roots and sometimes zeroes. Each of these values is a place where your function crosses the L-axis. C) Give an z-intercept where f(z) changes sign. (Only enter one z-intercept and only enter its z-value) D) Now give an z-intercept where f (r) does not change sign. (Only enter one r-intercept and only enter its c-value) DELL
