How do I solve so I can graph this? Should i set up an x_Y TABLE AND use -3... on for x? Sorry I missed the x^4th in the equation. How would I solve this with a graphing calculator?
Lori, I have one more way to "tackle" your problem. Has your class been introduced to Synthetic Division yet? If so, then you can line up the coefficients while trying the possible solution of x=1 (Factor of ( X-1)) 1/ 1 0 -4 0 3 You begin by bringing down the first column and 1 1 -3 -3 "synthesize" with multiplications & additions. 1 1 -3 -3 0 When you reach zero, you have a root! Now, you have the factors (X-1)and (X3 + X2 -4X -3) and you can try another root...say X=-1 (Footnote: I used the exponents behind the variable) -1/ 1 1 -3 -3 Continue the process until you can manage the -1 0 +3 remaining roots. Each bottom number comes 1 0 -3 0 from a multiplication & addition step. Now, the remaining factor is X2 - 3 which leads to X = sqrt(3).plus or minus Your factors would be (X-1)(X+1)(X2 - 3)= 0 This leads to X=1, -1, +- sqrt(3). I just wish I had seen your problem sooner...sorry! Charles S. 3/26/2013
