Question

Find the x- and y- intercepts of the following polynomial functions:

2. P(x) = x⁴ - 2x² + 1

3. P(x) = x (x- 1/2) (x + 4) (x - 1)

4. P(x) = x3 - 2x² - 4x + 8

5. P(x) = (x + 2) (x + 5) (x - 3) (x - 4)​

Answer 1

2. x-intercepts:(1,0),(-1,0) y-intercept:(0,1)

3.x-intercepts:(0,0),(1/2,0),(-4,0),(1,0) y-intercept:(0,0)

4.x-intercepts:(2,0),(-2,0) y-intercept:(0,8)

5.x-intercepts:(-2,0),(-5,0),(3,0),(4,0) y-intercept:(0,120)
