Question

From the graph determine the range

Answer 1

Answer: y <\= 0 >\= -3

Explanation:

Range is the highest and lowest y values in a graph.

The lowest y value is -3 and the highest y value is 0

P.s. <\= is just less than or equal to

Answer 2

Domain:

`(-4,4)`

Range:

`[-3,0]`

Explanation:

we are given a graph

Domain:

we know that domain is all possible values of x for which any function is defined

so, we will consider all possible values of x at which curve exists will be our domain

We can see that

smallest x-value is -4

and largest x-value is 4

But there is open circle at (-4,0) and (4,0)

so, domain will be

`(-4,4)`

Range:

we know that range is all possible y-values

so, we will consider all possible values of y at which curve exists will be our domain

smallest y-value is -3

and largest y-value is 0

and there is closed circle on them

so, range will be

`[-3,0]`
