First one is 33y^3-22y^2-27y+18
Second one is -3a^4-20a^2 x^2+7x^4
I hope this helps you :)
It's asking on the slope of it for the f⁻¹(x), so you have to get the inverse firstly, then we can simply get the derivative by implicit differentiation,
$500? because if you have 200 monthly and a 700 deductible
(2+7) x (2/5) (3) = x
9 x (2/5) (3) = x
9 x 1.2 = x
10.8 or 10 4/5 = x
