Answer:
f^-1(x) = (x +4)/3
Step-by-step explanation:
The inverse function is found by swapping x and y, then solving for y.
y = 3x -4 . . . . . function y = f(x)
x = 3y -4 . . . . . inverse relation
x +4 = 3y . . . . add 4
(x +4)/3 = y . . . divide by 3. This is the inverse function
f^-1(x) = (x +4)/3
Answer:
Option c
or 
Step-by-step explanation:
The absolute value is a function that transforms any value x into a positive number.
Therefore, for the function 
x> 0 for all real numbers.
Then the inequation:
has two cases
if 
(i)
if 
(ii)
We solve the case (i)
We solve the case (ii)
Then the solution is:
or
The given graph shows the relationship between the social media posts and grade point average of different students in Brent's class.
From the given graph, we can say that the grade point average of students decrease with increase in number of their social media posts.
Since grade point average decreases approximately linearly with increase in use of social media posts, It is Strong negative correlation.
Hence, option D is correct i.e. Strong Negative Correlation.
