| Question | Answer |
|---|---|
| f(x)= |x|-2 | vertical shift down by two units |
| f(x)= |x|+5 | vertical shift up 5 units |
| f(x)= |x| | parenting graph |
| f(x)= |x-8| | vertical shift to the right by 8 units |
| f(x)= |x+5| | vertical shift to the left by 5 units |
| f(x)= 9|x| | vertical strech |
| f(x)= -4|x| | vertical stretch, and reflection over the x axis |
| f(x)= -|x| | reflection over the x axis |
| f(x)= 4|x-3| | vertical shift to the right by 3 units, vertical strech |
| f(x)= -3|x|+6 | vertical strech, reflection over the x axis, vertical shift up by 6 units |
| What is f(x)? | another name for y |
| slope formula | y = mx + b |
| what is the slope and y intersept of y = 4x - 3 | y int= -3 slope= 4 |
| f(x)=1/3|x| | vertical shrink |
