use the quotient rule then after using it the first time use it again on your resulting equation, since you are looking for the second derivative
I ain't Joseph but what's wrong?
The answer is 532 full your welcome yay fun
The given equation is

x intercept
To find the x intercept, we have to plug 0 for y and solve for x.That is

So x intercept is (6,0) .
y intercept
To find the y intercept , we have to plug 0 for x and solve for y. That is

So the y intercept is (0,-9) .
