Use the rational zeros theorem to find the zeros of P of x = negative x cubed minus x squared + 5x minus 3. Then, use the zeros, the end behavior, and a few extra points to sketch its graph
Use the rational zeros theorem to find the zeros of P of x = 2x to the fourth power minus 9x cubed + 6x squared + 11x minus 6. Then, use the zeros, the end behavior, and a few extra points to sketch its graph
