The curve pass through the y-axis at the coordinate point (0, 10) showing that the y-intercept of the function is (0, 10)
<h3 /><h3>Graph of a polynomial</h3>
The graph of a polynomial function is a smooth continuous curve. The point where the curve intersects the x-axis is the zero of the polynomial.
A polynomial is also known to have a degree of 3 and above. Hence the given polynomial has a leading degree of 3 and expressed as:
f(x)=−x^3+x^2+9x−9
The graph of the function is as plotted below. From the function, you can see that the curve pass through the y-axis at the coordinate point (0, 10) showing that the y-intercept of the function is (0, 10)

Answer:
The inequality is
The greatest length of time Jeremy can rent the jet ski is 5 and Jeremy can rent maximum of 135 minutes.
Step-by-step explanation:
Given: Cost of first hour rent of jet ski is $55
Cost of each additional 15 minutes of jet ski is $10
Jeremy can spend no more than $105
Assuming the number of additional 15-minutes increment be "x"
Jeremy´s total spending would be first hour rental fees and additional charges for each 15-minutes of jet ski.
Lets put up an expression for total spending of Jeremy.
We also know that Jeremy can not spend more than $105
∴ Putting up the total spending of Jeremy in an inequality.
Now solving the inequality to find the greatest number of time Jeremy can rent the jet ski,
⇒
Subtracting both side by 55
⇒
Dividing both side by 10
⇒
∴
Therefore, Jeremy can rent for
Jeremy can rent maximum of 135 minutes.
The answer is C,
I think that’s eighth
