Question

Plz help im struggling in this lesson :( What graph represents the piecewise-defined function?

Answer 1

Well im not good at this ,butt I'll tell you something. An open dot means that point is not included , soo something like y<208 would mean 208 is not included and have an open dot, butt a closed dot means the point is included, such as <_ 450. ( The line is supposed to be under < butt i don't know how to do that.)  Hope this helps

Answer 2

Answer:

The piecewise function is not clear, so I will represent every function in the plots.

The Top left option:

y = 3 if x ≤ 1

y = x if x > 1

Top right option:

y = 3 if x < 1

y = 1 if x ≥ 1

Bottom left option:

y = 3 if x ≤ 1

y = 1 if x > 1

Bottom right option:

y = 3 if x < 1

y = x if x ≥ 1
