Explain how to write a function rule from the table below. then write a function rule.

x 2 4 6
y 1 0 –1

To find the slope you do y1-y2/x1-x2

To find the y intercept you look at when x is zero what is y.

Equation is y=-1/2x -2

732π cm^3

Step-by-step explanation:

Volume of the biggest cone

(15^2 * π *20)/3 = 1500π cm^3

Volume of the smallest cone

20^3 : 16^3= 1500π : x

x = (1500π * 4096)/8000= 768π cm^3

Volume of the frustum = 1500π - 768π = 732π cm^3
