    Evaluating Functions

    1) Let f be the function defined by F(x) = 2x^4+5. Find f(2a-h).

    So far I've gotten

    F(2a-h) = 2(2a-h)^4 + 5
    = 2(4a^4 - 8a^3h + 12a^2h^2 - 4ah^3 + h^4) +5

    Am I correct so far??

\left( {2a - h} \right)^2  = \left( {2a} \right)^4  - 4\left( {2a} \right)^3 h + 6\left( {2a} \right)^2 h^2  - 4\left( {2a} \right)h^3  + h^4 <br />
