Question 9: (2 points) Write an equation for a rational function with the given characteristics. Vertical asymptotes at z = -3 and r = 5, x-intercepts at (-5, 0) and (3, 0), horizontal asymptote at y Enclose numerators and denominators in parentheses. For example, (a - b)/ (1 + n). Include a multiplication sign between symbols. For example, a * r. f (I) =_ Question 10: (2 points) Simplify the expression. 27 Enter the exact answer. Hint: You can write roots as fractional exponents, for example - as (-64/27)(1/3). However, the answer to this question is a fraction without needing a root symbol. Question 11: (2 points) Simplify the expression. V10818 + V2728 Enter the exact answer. Hints: . You can write exponents with the ^ symbol, for example writing z as x^g . You can write square roots as sqrt, for example writing v 108 x as sqrt(108 x^8)
