The function f(x) is defined by the set of ordered pairs {(5,-2),(-6,-2),(3,-2),(4,-2)

Assuming it is a constant function.

Step-by-step explanation:

(5,-2)

(-6,-2)

(3,-2)

(4,-2)

From the points, we can see that for any value of , the function will give -2. The graph of this function will be a horizontal line, parallel to the -line passing the y-intersect point -2.

So the function might be

If it is a constant function.

I'm considering that there are no discontinuities.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
