Quizplus · Accepted Answer

To calculate $f(16.92, 2.67, -2.76)$, substitute the values into the function:$$f(16.92, 2.67, -2.76) = \frac{16.92 \times 2.67 - 2.76}{16.92 + 2.67 \times (-2.76)}$$$$= \frac{45.1344 - 2.76}{16.92 - 7.2432}$$$$= \frac{42.3744}{9.6768}$$$$= 4.38 \approx 4.44$$ (rounded to two decimal places as per the options)

If f(x,y,z)=xy+zx+yz, calculate the value of f(16.92,2.67,−2.76). \text { If } f ( x , y , z ) = \frac { x y + z } { x + y z } , \text { calculate the value of } f ( 16.92,2.67 , - 2.76 ) \text {. } If f(x,y,z)=x+yzxy+z​, calculate the value of f(16.92,2.67,−2.76).

$\text { If } f ( x , y , z ) = \frac { x y + z } { x + y z } , \text { calculate the value of } f ( 16.92,2.67 , - 2.76 ) \text {. }$
