4x + 4 rr-2r f(x)= An asymptote is a line, which means you must write an equation, not just a number. (a) Find all r-intercepts, vertical asymptotes, and holes. SHOW YOUR WORK. Use the bottom of this page or a separate sheet. vertical asymptotes x-intercepts holes (b) Find the horizontal or slant asymptote (if it exists). (c) Sketch f(x). Label the scale on the r-axis (i.c., say how far apart your tick marks are), but you don't have to draw a scale on the y-axis. Also draw any asymptotes. You will need to choose additional - values between and beyond the x-intercepts and vertical asymptotes and find y-values to get an idea of the shape of the graph; include those points on the chart below.
