We are given function:
Let us find it's inverse.
In order to find it's inverse, we need to get function equal to y.
Switching x and y's .
Now, solving it for y.
Dividing both sides by 6, we get
Taking square root on both sides, we get
Re-writing in the form of given inverse.
On comparing with given M^-1 = √((x/3k)+k).
k=2.
<h3>Therefore, correct option is C.) k = 2.</h3>
Z = (x - mean) / SD = (79 - 70) / 3 = 3
<span>P (Z > 3)? = 1 - F (z) = 1 - F (3) = 0.00135</span>
