This is about polynomial function

4. y = x2(x+3) (x+1) (x-1) (x-3) x-intercepts: y-intercept: X -4 -2 -0.5 2 4 y List all your answers above as ordered pairs.You have been provided illustrative examples of solving for the x- and y- intercepts, an important step in graphing a polynomial function. Remember, these intercepts are used to determine the points where the graph intersects or touches the x-axis and the y-axis. But these points are not sufficient to draw the graph of polynomial functions. Enjoy as you learn by performing the next activity. Determine the intercepts of the graphs of the following polynomial functions: 1. y = (x-1)(x2-5x+6) 2. y = (x - 2)(x - 1)(x + 3) 3. y = 2x4 + 8x3 + 4x2 - 8x - 6 4. y = x3+3x2-4x-12 5. y = x5 + 10x3 - 9x
