You can put this solution on YOUR website!
t%28x%29=5-x%5E3%2Bx;
What is t%28-1%29 ?

Use your function in decreasing powers of x as t%28x%29=-x%5E3%2Bx%2B5. For the value of t when x is -1, use Rational Roots Theorem or Remainder Theorem; or simply substitute for x and evaluate t.

Just making the substitution and evaluating is easiest for this exercise.
