Which table shows a function that is increasing only over the intreval (-2, 1), and nowhere else? Download docx

we know that

any function is increasing when for increase in x-values, y-value should also increase

we will verify each table

table-1:

we can see that

x increase as - 3, - 2, - 1, 0, 1,2

y is also increasing - 6,-3,-1,1,3,6

so, this is increasing

table-2:

we can see that

x increase as - 3, - 2, - 1, 0, 1,2

but it is asking between - 2 to 1

y-values are - 4,-1,1,4 ... which is increasing

so, this is increasing

table-3:

we can see that

x increase as - 3, - 2, - 1, 0, 1,2

but y changes from - 3 to - 5 ... which is decreasing

so, this is not increasing

table-4:

we can see that

x increase as - 3, - 2, - 1, 0, 1,2

but y changes from 7 to 1 ... which is decreasing

so, this is not increasing

awnser is b of course if you work out the problelm like i did
