Answer: Jacki did not subtract 12 from 8 correctly
Step-by-step explanation: it should be -4
Correct Answer:
3rd option is the correct answer
Solution:The zeros of the polynomial are -1,1 and 3. The multiplicity of 3 is 2. So the polynomial can be expressed as:

The y-intercept of the polynomial is -18. This means the polynomial passes through the point (0,-18). Therefore, y must be -18 when x = 0. Using these values of x and y in previous equation we get:

The final equation of the polynomial becomes:
Y=3x + 8.25
