x = -18 / 35
x= -0.5142857143
I'm guessing that b/c the answer is not an easy number that you probably are trying to do something else. .. ask again :)
23,000 * 12/100 = 23,000 * 0.12 = 2,760$
You would make 2,760$ in commisions

That’s what my tutor told me
Answer: ![f'(-3)=538](https://tex.z-dn.net/?f=f%27%28-3%29%3D538)
Step by step:
To get the derivative you can either multiply out the product (which I did below), or apply the formula for the derivative of a product of two functions. Either way you will obtain the same result, of course.
![f(x) = (2x^2-7x)(-x^2-7)=-2 x^4 + 7 x^3 - 14 x^2 + 49 x\\f'(x) = -8x^3 +21x^2 - 28x +49\\f'(-3)=538](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%282x%5E2-7x%29%28-x%5E2-7%29%3D-2%20x%5E4%20%2B%207%20x%5E3%20-%2014%20x%5E2%20%2B%2049%20x%5C%5Cf%27%28x%29%20%3D%20-8x%5E3%20%2B21x%5E2%20-%2028x%20%2B49%5C%5Cf%27%28-3%29%3D538)
