What is the range of the function on the graph

all real numbers less than or equal to 3

Step-by-step explanation:

The range of the function is set of all y value for which the function is defined

To find out the range we look at the maximum or minimum point on the graph

Maximum point on the graph that is vertex is (-1,3)

x=-1 and y=3

The graph of y is below 3 (vertex)

So the range of the function is set of all real numbers less than or equal to 3

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.
