4. The sale price of shrimp at a local grocery store is $1.15 for the first ounce and $0.95 for each additional ounce. Which function rule shows how the cost of shrimp, y, depends on the number of ounces, x?
1. how did you get 24 ?
f(x) = x^2 - 3x + 2
f(-2) = (-2)^2 - 3(-2) + 2
= 4 + 6 + 2 = 12
2. E = 12m
4. y = 1.15 + .95(x-1)
Omg thank you so much!!
