18. Answer: $0.25 per topping
<u>Step-by-step explanation:</u>
Choose any 2 points. I chose (2, 3.00) and (4, 3.50)
Use the slope formula to find the rate:
rate = ![\frac{3.50-3.00}{4-2}](https://tex.z-dn.net/?f=%5Cfrac%7B3.50-3.00%7D%7B4-2%7D)
= ![\frac{0.50}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B0.50%7D%7B2%7D)
= ![\frac{0.25}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B0.25%7D%7B1%7D)
Answer:
- 66
Step-by-step explanation:
Evaluate g(- 4) then substitute the value obtained into f(x) , that is
g(- 4) = - 2(- 4)² = - 2 × 16 = - 32, then
f(- 32) = 2(- 32 - 1) = 2 × - 33 = - 66
