1. Find (f - g)(x) where f(x) = -X2, g(x) = -(x + 4)2. O (f - g)(x) = -2x2 + 8x + 16
O (f - g)(x) = -8x – 16
O (f - g)(x) = -2x2 – 8x - 16
O (F-9)() = 8x + 16

I'm at a bookstore with $\$35$ in my pocket and a $20\%$-off coupon. what is the cost of the most expensive book i can buy with my money and the coupon? (assume that there are books of every possible price in the bookstore. it's a large bookstore! )
