Answer:all real numbers

Step-by-step explanation: f(x) =3 means that Y is 3 for every value of X, as there's no X affected in the formula, so it will have that value always.

As there are also no restrictions, like 1/X or logX then you know that every value of X is possible to be replaced in f(x) fórmula [if there were any X in the formula, which is not the case]

Answer:

$Cost = 112.266$ cent/km

Step-by-step explanation:

Given

$Unit\ cost = R17.82/litre$

$Rate = 6.3litre/100km$

Required

The fuel cost in $cent\ per\ km$

This is calculated using:

$Cost = Unit\ cost * Rate$

$Cost = R17.82/litre * 6.3litre/100km$

$Cost = R17.82 * 6.3/100km$

$Cost = R1.12266/km$

Multiply by $100$ to get the cost in cents

$Cost = 1.12266 * 100$ cent/km

$Cost = 112.266$ cent/km
