Answer:
[tex]k=x[/tex]
Step-by-step explanation:
We are given that [tex]k=f(z),z=f(x)[/tex]
We have to find the value of x.
Suppose
[tex]z=f(x)=x^2[/tex]
[tex]z=x^2[/tex]
[tex]x=\sqrt z[/tex]
[tex]x=f(z)[/tex]
We are given that [tex]k=f(z)[/tex]
Substitute the value then we get
[tex]k=x[/tex]
Hence,[tex]k=x[/tex]
