Using complete sentences, explain how to graph the following piecewise function:
y = x2 if x < 1
y = 3x if x greater than or equal to 1

Answer 1

Thank you for your time.

Answer 2

y = x^2 if x < 1

so you graph y = x^2, but you only graph it for values of x less than 1 (so you erase the portion to the right of x = 1)

Answer 3

similarly, you plot y = 3x, but only for x values that are greater than or equal to 1

Answer 4

That is it

Answer 5

yeah basically

Answer 6

OK thank you. But one thing is their a more extraneous explanation.

Answer 7

what do you mean

Answer 8

A longer more detailed solution or is that smack up just it.

Answer 9

you could go in more detail, but that's the basics of it

Answer 10

you could explain that x^2 is plotted from a series of points

and so is y = 3x

Answer 11

y = 3x only needs 2 points but x^2 needs about 5 or 6 to get an idea of the shape of the graph

Answer 12

If it is not to much I would prefer the longer explanation.

Answer 13

you could do it like this:

use these x values and plug them into the piece wise function

-3, -2, -1, 0, 1, 2, 3

the values -3, -2, -1, 0 will go into y = x^2 to get corresponding y values

so you'll have a bunch of points which will then be connected with a curve to graph y = x^2

Answer 14

the values x = 1, x = 2, x = 3 will go into y = 3x and they will generate points to help graph y = 3x

Answer 15

Thank you.

Answer 16

Ok that is perfect thank you.

Answer 17

Was this a good question.

Answer 18

what do you mean?

Answer 19

Was it a rare type. You do not find piece wise functions a lot do you.

Answer 20

oh I've seen a lot of piece wise function questions, so not really

Answer 21

but today is the first time I've seen it, so I guess it's not as common

Answer 22

Oh well I thought it was really rare.?!

Answer 23

hmm not really

Answer 24

Thank you. One thing if it is not a lot can I get a medal for asking please.

Answer 25

sure

Answer 26

Thank you

Answer 27

Bye
