step one: find the domain of each piece,

step two: find the equation that describes the interval on each domain

step three: combine

ill give you a different example

|dw:1360553796475:dw|

unklerhaukus · Answer

|dw:1360554027098:dw|

the domain for the first piece is 0≤x≤2
the equation for this interval is y=x

the domain for the second piece is 2≤x
the equation for the second piece is y=2

unklerhaukus · Answer

combining $$y=\begin{cases}x&0≤x≤2\2&2≤x\end{cases}$$

makes sense?

anonymous · Answer

yes!! a million times yes!! let me work it out! thank you so much, about to give up.

anonymous · Answer

can you help me with number 1 on my link above? just to know im doing it right?

unklerhaukus · Answer

what have you got so far?

anonymous · Answer

for the first one i got $$f(x) = \left\{ 3 ;  0 \le x \le 3\right\}$$

anonymous · Answer

and $$\left\{ x ; 3\le x \le 6 \right\}$$

unklerhaukus · Answer

what did you get for the equation of the second interval ,  y=x? thats not right

anonymous · Answer

how?

unklerhaukus · Answer

i mean y=-x+7

the slope is -1

and the y- intercept would be at y=7

anonymous · Answer

how did you get that thou/
