The function is given to be:

QUESTION A
The zeroes of the function are gotten when the function is equal to 0:

Therefore, we can calculate the zeroes when:

Dividing both sides by -9, we have:

Recall the Zero-Product Principle:

Therefore, we have that:

and

The zeroes are -1, 8.
The multiplicity of -1 is 2 and the multiplicity of 8 is 1.
QUESTION B
The graph of the function is shown below:
On observation of the graph, we can see that the graph touches the x-axis at x = -1, and it crosses the x-axis at x = 8.
Therefore, the graph crosses the x-axis at the larger x-intercept and the graph touches the x-intercept at the smaller x-intercept.
QUESTION C
The maximum number of turning points of a function is seen from the graph.
The maximum number of turning points on the graph is 2.
