Let f(x) = x2 - 16. Find f-1(x).

Arisa [49]

$f(x)=x^2-16$

To find $f^{-1}(x)$ , (the inverse of the function) you need to first replace the f(x) with y...
$y=x^2-16$
Then switch the x and the y.
$x=y^2-16$
Solve for y.
$x+16=y^2$
Take the square root of each side...
$\boxed{y=\pm\sqrt{x+16}}$

Question 4

Ilia_Sergeevich [38]

Answer:

Step-by-step explanation:

Given

See attachment for chart

Required

Number of off days

To do this, we simply calculate the expected value of the chart.

This is calculated as:

$E(x) = \sum x * f$

Where

x = days

f = chances

So, we have:

$E(x) = 0* 0.3 + 1 *0.2 + 2 * 0.25 + 3 * 0.2 + 4 * 0.02 + 5 * 0.01 + 6 * 0.01 + 7 * 0.01$

$E(x) = 1.56$

$E(x) \approx 2$
