Based on the names, could you guess what y intercept and x intercept are?

[rotund peak]

i think the y intercept one is like where the point crosses the y axis

and ther x crosses the x axis

[lone forge]

Yeah, already got two right there

Now what what would you match the constant interval, increasing interval and decreasing interval to?

[rotund peak]

[lone forge]

But which statement on the right would you match it to?

[rotund peak]

[lone forge]

What about the other two interval ones

[rotund peak]

i think i got

it

right?

also

idk how to find

domain

or range

or the increasing intervals

[lone forge]

Looks right to me

[rotund peak]

thanks thanks

but

how would i find domain

[lone forge]

From the previous definition, domain is the set of all x values shown on the graph right? So what values of x is the line on top/below of?

[rotund peak]

i dont follow sorry

[lone forge]

The function (blue line) starts at 5 with a shaded circle which means it’s included, and doesn’t have an end, denoted by the arrow

In set notation [] means inclusive () means exclusive

So the function goes from x = 5 to x = inf
