Equations are used to represent functions, and vice versa.
The equation of y as a function of x is [tex]y=\sqrt{6 - x^2[/tex]
The function is given as:
[tex]\sqrt{6-y^2}=x[/tex]
Square both sides
[tex]6-y^2=x^2[/tex]
Subtract 6 from both sides
[tex]-y^2=x^2 - 6[/tex]
Multiply both sides by -1
[tex]y^2=6 - x^2[/tex]
Take square root of both sides
[tex]y=\sqrt{6 - x^2[/tex]
Express as a function
[tex]f(x) = \sqrt{6- x^2[/tex]
Hence, the equation of y as a function of x is [tex]y=\sqrt{6 - x^2[/tex]
