Answer:
Answer C:
Step-by-step explanation:
Notice that all the functions look like x plus a constant in the numerator, and x minus the same constant in the denominator.
So we can do a general analysis finding the inverse of a function of the form:
and finding which value of "a" will make
To find the inverse we need to solve for "x" in the equivalent equation:
Then, we see that if , then the expression for
Then the function that verifies this condition is:
Answer:
A
Step-by-step explanation:
We are given the two functions:
And we want to find:
Recall that this is equivalent to:
Substitute and evaluate:
In conclusion, our answer is A.
11- do improper fraction so it would be -209/8 and 11/2 then do reciporcal of 11/2 to 2/11 then change divison sign into mulitplication sign so it should be like thsi h-209/8*2/11 then cross divide so it should be 19/4*1/1= 19/4= 4 3/4
