Answer:
- crosses at (1, 0)
- crosses at (-4, 0)
- touches at (-5, 0)
Step-by-step explanation:
The worksheet tells you the answers.
__
If the power of (x -k) is odd, the graph crosses the axis.
factors (x -1) and (x +4)^3 have odd powers, so the graph crosses where these factors are zero
__
If the power of (x -k) is even, the graph touches the axis.
factor (x +5)^2 has an even power, so the graph touches where that factor is zero.
