Steps in Graphing a Transformation of a Tangent Function
1) Do you know the shape of the final graph? (Is it a reflection of tangent or not?) 2) Do you know the length of the period? (pi/b=period) 3) Do you know the phase shift? (-c/b = phase shift) 4) Do you know TWO of the asymptotes? solve -pi/2 =bx+c and pi/2=bx+c 5) Do you know ALL of the asymptotes? x = asymptote +period*n with n being an integer 4) Can you find three points that lie on the intended graph of the transformation? 5) Do you know where the midline is? (y = d) 6) Do you know what the sign of a tells you about the location of the points of the graph of the transformation? (Is a is negative? Where does the special points live on the graph?)
