Question

Look at the graph of the function. Select the appropriate domain AND range

Answer 1

Correct options are B) Domain
`-4\leq x\leq 4` and , G) Range
`-3\leq y\leq 4` .

Explanation:

Here we need to find domain and range of a function whose graph is given below . Let's find out:

Domain : We know that domain of a function is the values of x for which we get the values of y which are always defined !

Range: We know that range of a function is all the values of y we get from the values of x . Or set of values of y .

For the given graph , Let's look at :

Value of x ( Domain )

Here we clearly see that graph is horizontally from x= -4 to x= 4. Hence domain is
`-4\leq x\leq 4` .

Value of y ( Range )

Here we clearly see that graph is vertically from y= -3 to y=4 . Hence Range is
`-3\leq y\leq 4` .

So , Correct options are B) Domain
`-4\leq x\leq 4` and , G) Range
`-3\leq y\leq 4` .
