Answer:
Option (D)
Step-by-step explanation:
In a function y shows the values of the function (Output values) and x shows the (input values).
Therefore, to convert any equation into the function, we will solve the equation for y.
Given equation is,
680x + 10y - 1000 = 0
680x + 10y = 1000
68x + y = 100
y = -68x + 100
Now replace y by f(x).
Therefore, the function will be,
f(x) = -68x + 100
Option (C) will be the correct option.
