Answer:
The graph of the inverse of function would be same.
Step-by-step explanation:
We have been given graph of function . We are asked to graph the inverse of our given function.
To find the inverse of a function, we will interchange the x and y variables and solve for y.
Upon interchanging variables, we will get:
Upon multiplying both sides of our equation by y, we will get:
Now, we will divide both sides of our equation by x as:
Since the inverse of our given function is same as function , therefore, the graph of the inverse of function would be same.
Answer :
Explanation:
Since we have given that
n(U) = 120, where U denotes universal set ,
n(F) = 45, where F denotes who speak French,
n(S) = 42 , where S denotes who speak Spanish,
n(F∪S)' = 50
n(F∪S) = n(U)-n(F∪S) = 120-50 = 70
Now, we know the formula, i.e.
n(F∪s) = n(F)+n(S)-n(F∩S)
⇒ 70 = 45+42-n(F∩S)
⇒ 70 = 87- n(F∩S)
⇒ 70-87 = -n(F∩S)
⇒ -17 = -n( F∩S)
⇒ 17 = n(F∩S)
