Test of a horizontal line.Suppose f is a function.F does not have an inverse if any horizontal line crosses the graph of f more than once.F does have an inverse if no horizontal line crosses the graph of f more than once
How do you calculate f's inverse?
- Finding a Function's Inverse
- Replace f(x) with y first, then.
- Every x must be replaced with a y, and vice versa.
- Solve the y-part of the equation from step two.
- In place of y, write f1(x) f 1 (x).
- Check that (ff1)(x)=x (f f f 1) (x) = x and (f1f)(x)=x (f f 1 f) (x) = x are both true to validate your work
f= {(1,2),(2,3),(3,5),(4,7)}
Dom(gof)=dom(f)={1,3,4}.
(gof)(1)=g{f(1)}=g(2)=3,
(gof)(3)=g{f(3)}=g(5)=1
(gof)(4)=g{f(4)}=g(1)
∴gof={(1,3),(3,1),(4,3)}.

Answer:
x=y−5z
Step-by-step explanation:
y=5z+x
Step 1: Flip the equation.
x+5z=y
Step 2: Add -5z to both sides.
x+5z+−5z=y+−5z
x=y−5z
Answer:
x=y−5z

Step-by-step explanation:
That is the answer and I know 100% that it is correct
The mad is 9
the mean is 4.5
then calculate all differences and you get 9
