Sketch the graph of the polynomial (given on the Quizizz Review)

For < and ≤ , select the intervals BELOW the x-axis

For > and ≥ , select the invervals ABOVE the x-axis

Remember: Less than symbols point Left

Use ( ) for open circles < and >

Use [ ] for closed circles ≤ and ≥

If dividing by x - 5, the value 5 would go in the top-left box

The number in the bottom right box is the remainder

If the remainder is zero, then the # in the top left box is a zero

f(-2), the y-value when x=-2, is equal to the remainder of synthetic division with -2 in the top-left box
