Answer:
![P(A\ or\ B)=\frac{7}{9}](https://tex.z-dn.net/?f=P%28A%5C%20or%5C%20B%29%3D%5Cfrac%7B7%7D%7B9%7D)
Step-by-step explanation:
We need to use the formula to calculate the probability of (A or B) where
A=Probability a student likes pepperoni
B=Probability a student likes olive
A and B =Probability a student likes both toppings in a pizza
A or B =Probability a student likes pepperoni or olive (and maybe both), a non-exclusive or
The formula is
![P(A\ or\ B)=P(A)+P(B)-P(A\ and\ B)](https://tex.z-dn.net/?f=P%28A%5C%20or%5C%20B%29%3DP%28A%29%2BP%28B%29-P%28A%5C%20and%5C%20B%29)
Since 6 students like pepperoni out of 9:
![P(A) = \frac{6}{9}](https://tex.z-dn.net/?f=P%28A%29%20%3D%20%5Cfrac%7B6%7D%7B9%7D)
Since 4 students like olive out of 9:
![P(B) = \frac{4}{9}](https://tex.z-dn.net/?f=P%28B%29%20%3D%20%5Cfrac%7B4%7D%7B9%7D)
Since 3 students like both toppings out of 9
![P(A\ and\ B) = \frac{3}{9}](https://tex.z-dn.net/?f=P%28A%5C%20and%5C%20B%29%20%3D%20%5Cfrac%7B3%7D%7B9%7D)
Then we have
![P(A\ or\ B)=\frac{6}{9}+\frac{4}{9}-\frac{3}{9}](https://tex.z-dn.net/?f=P%28A%5C%20or%5C%20B%29%3D%5Cfrac%7B6%7D%7B9%7D%2B%5Cfrac%7B4%7D%7B9%7D-%5Cfrac%7B3%7D%7B9%7D)
![P(A\ or\ B)=\frac{7}{9}](https://tex.z-dn.net/?f=P%28A%5C%20or%5C%20B%29%3D%5Cfrac%7B7%7D%7B9%7D)
through my calculations x=8
Because the graph is shifted up three units from the original mother function (f(x) = log x), and therefore, the answer is f(x) = log x + 3.
