Evaluate the function f(x) = x" + 2x + 8 at the given values of the independent variable and simplify. a. f(3) b. f(x+2) c. f(-x) a. f(3) = (Simplify your answer.) b. f(x + 2) =] (Simplify your answer.) C. f( - x) = (Simplify your answer.)Find the vertical asymptotes, if any, and the values of x corresponding to holes, if any, of the graph of the rational function. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (Type an equation. Use commas to separate answers as needed.) (O A. Thevertical asymptote(s) is(are) | |. There are no holes. (O B. The vertical asymptote(s) is(are) and hole(s) corresponding to (O . There are no vertical asymptotes but there is(are) hole(s) corresponding to D. There are no discontinuities. The following function is given. fix)=x" - 3% - 25x+75 a. List all rational zeros that are possible according to the Rational Zero Thearem. (Use a comma to separate answers as neaded.) b. Use synthetic division to test several possible rational zeros in order to identify one actual zero. One rational zero of the given function is |:| (Simplify your answer.) c. Use the zero from part (b) to find all the zeros of the polynomial function. The zeros of the function f{x) = x3 - 3){2 -25x+75 are |:| (Simplify your answer. Type an integer or a fraction. Use a comma to separate answers as needed.)
