Functions
What is a one to one function?
One to one function is when one x value has only one y value. It has to be this way and be a function for it to be one to one
Will an equal to sign have an open or closed circle on the number line
It will have a closed circle
what is the first step to solve 5(3y-4)-2=2(4y+1)
The first step is to distribute
solve 3(2x+5)=2(3x-4)=7
no solution
What is the first step to solve
4y-7=2y+9
The first step is to subtract 2y from both sides
What is the range

R={4,5,7}
Is this symbol a less then or greater than sign
>
greater than
Inverse operation of division is what?
The inverse is multiplication
What is the last step to solve an multi step equation with distribution?
The last step is to isolate the variable and solve for it
Solve 3x+5=2x+10
x=5
What is a function

What is compound inequalities
inequalities that have been joined by the words “and” or “or"
What is a multi step equation
It is an algebraic equation that requires more than one operation

solve 7m+5=3m+21
m=4
What is one way you can see a function?
A graph
What does the sign look like if it is equal to?
The sign will have a line under it
What is the inverse operation of subtraction?
The inverse is addition
Solve 4 (2y-3)+5=3(3y+1)-2
y=-8
Solve 5x+3=3x+11
x=4

Which one is the less than sign
1.<
2.>
1
solve 4(2x-3)+5=3(x+7)
x=5.6
5(3x+2)-4=2(6x-1)+10
true or false x= 2/3
true
