Given f(x)= 3x+2, what is the Inverse Function?
Grace [21]

Answer:

Step-by-step explanation:

For this case we must determine the inverse of the following function:

f(x)=3x-2

Step 1:

We would write

y=f(x) or y=3x-2

Step 2:

We clear x:

y+2=3x

\frac{y+2}{3}=x

Step 3:

"x" and "y" are exchanged:

y=\frac{x+2}{3}

The inverse is:

f^{-1}(x)=\frac{x+2}{3}

The heights of the children at a summer camp are normally distributed with a mean of 54 in. and a standard deviation of 2.4 in.
Andreyy89
The z-score is a measure of how many standard deviations the value is from the mean. A z-score of 1.5 means that the value is 1.5 standard deviations above the mean. 

<span>1.5 x 2.4 = 3.6 </span>
<span>54 + 3.6 = 57.6 </span>

<span>Answer: </span>
<span>57.6 in </span>

<span>The formula is: </span>
<span>x = zσ + μ </span>

<span>z : z-score (1.5) </span>
<span>σ : standard deviation (2.4) </span>
<span>μ : mean (54) </span>

<span>Answer: </span>
<span>x = 57.6</span>
