The recommended daily intake rdi a nutrients supplement for a certain age group is 800 mg per day actully supplements needs vary
QveST [7]

Answer:

C

Step-by-step explanation:

The recommended daily intake of a nutrients supplement for a certain age group is 800 mg per day.

Actully supplements needs vary from person to person  plus or minus 50 mg.

This means the minimum value is 800 - 50 = 750 mg per day and the maximum value is 800 + 50 = 850 mg per day.

Let x mg be a possible daily amount of nutrients supplement. Then

750\le x\le 850

Subtract 800:

750-800\le x-800\le 850-800\\ \\-50\le x-800\le 50

This inequality can be rewritten using absolute value notation as

|x-800|\le 50

Given the function f(x) = 4(x+3) − 5, solve for the inverse function when x = 3. (1 point)
atroni [7]

the function f(x) = 4(x+3) − 5

Lets find the inverse function f^-1(x)

step 1: Replace f(x) with y

y = 4(x+3) − 5

step 2: Replace x  with y and y with x

x = 4(y+3) - 5

step 3: Solve for y

x = 4(y+3) - 5

x = 4y +12 -5

x= 4y + 7 (subtract 7 on both sides)

x - 7 = 4y (divide by 4 on both sides)

\frac{x-7}{4}=y

f^{-1}(x)=\frac{x-7}{4}

Given : x = 3

We plug in 3 for x in the inverse function

f^{-1}(x)=\frac{3-7}{4} = -1

the inverse function when x = 3  is -1
