Answer:
so the top two is 4.0
and the bottom two are 4.0
x-intercepts: (1,0), (2,0), (5,0)
y-intercepts: (0,-10)
Step-by-step explanation:
One factor of the function is
Factor the polynomial in the following way:
Now factor the quadratic in brackets:
Hence,
The x-intercepts are points at which y = 0, so
The y-intercepts are points at which x = 0, so
