i would use the book and notes to show them what a piecewise function is.
Hello my name is Diallo and im here to teach you how to do piecewise functions. First you evaluate te problem. Then you solve for the problem by plugging in with the your given problem.
I would look at my notes i took

i would use my book and notes to shoew them what and how it would be done.
F(x)={x+2 when x<2 or 2x+1 when x>2}
F(0)=0+2
F(0)=2
F(2)=2(2)+1
4+1
F(2)=5
F(-4)=2(4)+1
8+1
F(-4)=9

yeah, not really understanding what peicewise really is
Piecewise fractions when people see the word "FRACTION' people already start to make frowny faces and say things about. Because i'm one of those people. But i can show a person an easy way to do piecewise fractions here's an example:
Evalute: y=x+4
when x=2
y=2+4
=6
That's all or
evaluate f(x)= {2x+1 when x>1
{x when x <_ 1
when x=7
f(7)= 2(7)+1
= 14+1
f(7)=15
That's all it's just that simple..

there is a greater than and less than option. Which ever function applies to the equation than that is the one you use. You plug in and go! Thats about it.

Hey, this is Derek Tharpe, I need my grade. x means that any number can go there.
step 1 find slope. y2-y1/x2-x1
step2 pick one of the 2 parts.
step3. plug in for slope and then use y-y1=m(x-#)
step4 solve

i will use my notes to help me.

Evalute: y=x+9
when x=5
y=9+5
=14
That's all or
evaluate f(x)= {2x+1 when x>1
{x when x <_ 1
when x=7
f(7)= 2(7)+1
= 14+1
f(7)=15
thats how you solve it!!1!!

if you have a problem that is less than or equal to then you would multiply that number by 3 if you have a problem that is greater than ten, then you would multiply by seven
To solve piecewise functions, first you must look at the problem. For example:
Evaluate y=x+4 when x+2.
You plug it in and solve, and get the answer y=6.
To solve more complicated problems, like:
Evaluate f(x) = 2x+1 when x>1
x when x<=1
when x=7
You basically find the problem it applies to, then plug-in and solve and get your answer.

tell them to look at their notes

Basically, you will follow the steps, and you have your answer. You will plug in the formula you are given and solve the problem. It's an easy method to understand. *Anjellica S.*

Since i can not rememeber from the top of my brain i would kindly show the people my notes and explain how to do it
i have no idea

yah i do not understanding it so i need to come after class sometime to getit stephen hurst #78
