Lynn has a watering can that holds 16 cups of water, and she fills it half full. then she waters her 15 plants so that each plan

professor190 [17]

Has 16 cups of water that is half full.
16/2 = 8
Watering can then has 8 cups of water in it.
This number needs to be divided by 15 plants.
The answer is 8/15 of a cup of water per plant which is also 0.53 cups per plant.

Complete the data table for the function f(x) = -x - 2 + 2.

alexgriva [62]

Given the following function:

$\text{ f(x) = }\sqrt[]{-x\text{ -2}}\text{ + 2}$

y = f(x)

Therefore, let's complete the data table by substituting each x-values to be able to get the respective y-values,

We get,

At x = -2,

$\text{ y = f(x) = }\sqrt[]{-x-2}\text{ + 2}$ $\text{f(-2) = }\sqrt[]{-(-2)-2}\text{ + 2}$ $\text{ = }\sqrt[]{2\text{ - 2}}\text{ + 2}$ $\text{ = }\sqrt[]{0}\text{ + 2}$ $\text{ y = f(-2) = 2}$

Therefore, y = 2 at x = -2.

At x = -3,

$\text{ y = f(x) = }\sqrt[]{-x-2}\text{ + 2}$ $\text{f(-3) = }\sqrt[]{-(-3)-2}\text{ + 2}$ $\text{= }\sqrt[]{3-2}\text{ + 2}$ $\text{= }\sqrt[]{1}\text{ + 2}$ $\text{= }1\text{ + 2}$ $\text{ f(-3) = 3}$

Therefore, y = 3 at x = -3.

At x = -6,
