calculate the value of $f ( 9.52,1.93 , - 1.76 )$
A) 2.71
B) 14.79
C) -1.65
D) 18.09

Plugging the values into the function $f(x, y, z) = \frac{xy + z}{x + yz}$, we get $f(9.52, 1.93, -1.76) = \frac{9.52 \times 1.93 - 1.76}{9.52 + 1.93 \times (-1.76)}$. Calculating the numerator and denominator separately and then dividing them gives approximately 2.71.

If f(x,y,z)=xy+zx+yzf ( x , y , z ) = \frac { x y + z } { x + y z }f(x,y,z)=x+yzxy+z​

If $f ( x , y , z ) = \frac { x y + z } { x + y z }$
