Question:

Evaluate the function.

Find {eq}f (3,\ 2,\ 8) {/eq} when {eq}f (x,\ y,\ z) = 3 x^2 + 3 y^2 - z^2 {/eq}.

Evaluating the Function:

A mathematical function represents the relationship between the dependent and the independent variables. It may have one or two or three independent variables i.e. (x,y,z).

To evaluate the function at any given point (x, y,z), we have to put the values of independent variables in the given function.

Given:

{eq}* f (x,\ y,\ z) = 3 x^2 + 3 y^2 - z^2 \\ {/eq}

{eq}* x= 3 , \ y = 2 , \ z = 8 \\ {/eq}

On putting the values of 'x', 'y' ,'z' in the...
