Consider the multivariable function f\left(x,y,z\right)=\frac{x^3-2.5y^2+\frac{z}{2}}{z\left(x-y\right)}f ( x , y , z ) = x 3 −
Lelu [443]

Answer:

f\left(2,3,1\right)=\bold{14}

Step-by-step explanation:

Given the function:

f\left(x,y,z\right)=\frac{x^3-2.5y^2+\frac{z}{2}}{z\left(x-y\right)}

To find:

The value of f(2, 3, 1) = ?

Solution:

f(2, 3, 1) means the values of x, y\ and\ z as:

x=2\\y=3\\z=1

Let us put the given values in the given function and let us solve for it:

\Rightarrow f\left(2,3,1\right)=\dfrac{2^3-2.5\times 3^2+\frac{1}{2}}{1\left(2-3\right)}\\\\\Rightarrow f\left(2,3,1\right)=\dfrac{8-2.5\times 9+0.5}{1\left(-1\right)}\\\\\Rightarrow f\left(2,3,1\right)=\dfrac{8-22.5+0.5}{-1}\\\\\Rightarrow f\left(2,3,1\right)=\dfrac{-14}{-1}\\\\\Rightarrow f\left(2,3,1\right)=\bold{14}

Therefore, the answer is:

f\left(2,3,1\right)=\bold{14}
