Answer:
f^(-1)(x) = 3x/(2-x)
Step-by-step explanation:
f(x) = 2x/(x+3)
f(x)*(x+3)=2x
x(2-f(x))=3f(x)
x=3f(x)/(2-f(x))
f^(-1)(x) = 3x/(2-x)
Question 3)
Given
The point (1, -5)
The slope m = -5/6
Using the point-slope form of the equation of a line

where
- m is the slope of the line
In our case:
substituting the values m = -5/6 and the point (1, -5) in the point-slope form of the equation of the line



Thus, the point-slope form of the equation of the line is:

Question 4)
Given
The point (-1, 5)
The slope m = -7/2
In our case:
substituting the values m = -7/2 and the point (-1, 5) in the point-slope form of the equation of the line



Thus, the point-slope form of the equation of the line is:
