Pg. 369 #32 R(x) = (X4) / (X2 - 9) Step 1: < FACTOR > R(x) = (X4) / (X2 - 9) R(x) = (X4) / (x-3)(x+3)
Step 2: FIND THE DOMAIN R(x) = (X4) / (x-3)(x+3) You have (x-3)(x+3) in the Denominator So set them equal to Zero x-3 = 0 and x+ 3= 0 x ≠ 3 x ≠ -3 The Domain is all real numbers except: x = 3 and x = -3
Step 3: Find the Vertical Asymptotes Take the Denominator of the Function R(x) = (X4) / (X2 - 9) and set it equal to zero X2 – 9 = 0 X2 = 9 √x2 = √9 X = 3 and -3
So since X = 3 and X= -3 then that means the function R(x) = (X4) / (X2 - 9) Has two vertical asymptotes One at X = -3 and the other at X = 3
Step 4: Finding the Horizontal Asymptotes To find the Horizontal Asymptotes of the Function R(x) = (X4) / (X2 - 9) Compare the Degrees of the numerator and the denominator In this case The Numerator has aX4with a degree of 4 The Denominator has X2 with a degree of 2
Therefore : The N(4) > D(2) So according the Rule about Horizontal Asymptotes In which the degree of the numerator is n and degree of the denominator is m. If n > m + 1 That tells you that the Graph of R has neither a horizontal behavior nor an oblique asymptote. So NO Horizontal Asymptote for R(x) = (X4) / (X2 - 9)
Step 5: Finding the x and y intercepts of R(x) = (X4) / (X2 - 9) For the x-intercept Set R(x) = (X4) / (X2 - 9) = 0 and solve (X4) / (X2 - 9) = 0 (X4) = 0 4√(X4= 4√0 X= 0 Therefore the x-intercept for R(x) = (X4) / (X2 - 9) Is (0, 0)
For the y-intercept Plug in Zero in place of X R(x) = (X4) / (X2 - 9) to find the x coordinate R(x) = (04) / (02 - 9) y = (0) / (- 9) y = 0 Therefore the y-interceptfor R(x) = (X4) / (X2 - 9) Is (0,0)
R(x) = (X4) / (X2 - 9) X-intercept (0,0) and Y-intercept (0,0)
