| A | B |

| What shape is a parabola ? | It has a U shape. |
| Does the parabola go up or can it go down ? | It can go either way. |
| What is the generag parabola formnula ? | y= ax2 +bx+c a can not be 0 if a is zero then this is a line formula! |
| What information can you get from a parabola equation ? | vertex,axis of symmetry, whetehr it is up or down and location of other points |
| What is the formula for x vereex ? | x=-b/2a |
| How do you get the y-vertex ? | Plug x vertex value into formulaa |
| What is vertex ? | That point where parabola hits it maximum peak or minimum point. |
| When does parabola look like an upward smiley face ? | When coeficient a is postive |
| When does parabola look like a frown ? | That occurs when a value is negative. |
| How to get the location of axis of symmetry ? | It is halway point of the intercepts of the X axis. |
| if you see the formula y=xsquared +C what happens to the location of parabola ? | It moves up by that value ? |
| What happens when y equal x2- C ? | Tit moves down by that value. |
| What happens when the value for k gets bigger in formula y=kx2 | Then parabola gets more |
| When you get rid of a suared value by taling a square root what happens to the value of the numeber ? | It always become a = and a - value !!!! |
| How do you extract roots to soleve quadratic ? | 2x2-5 =7 get rid of - 5 buy adding to both sides then you have 2x2=12 divide by 2 and get the x2 value= 6 squar root both side gets x = =/ square root of 6 !!!! |
| What is eextraction of root method ? | Isolate the x squared value to one side of equattion then get square root !! |
| Cna you use extraction of root when the x squared value is a fraction ? | Yes do algebra and isolate the xsquared value. |
| If an x minus a value is squares can you coleve it vy extracting roots ? | Yes treat the entire set in paranthesis an get square root and then solve ! Remeber when the number on the other side of equation is squared it becomes +/- !!! |
| What is compound interest formula ? | Ammount after x number of years is equat to value you put in account known as princial (1+interest rate) raised to the power of numer of years it is in the account !!! |
| What is zero factor principle ? | If multiply any two nuimber by a zero the product is zero ! |
| To solve a quatradic equation using factoring what must happemn ? | Rearrange formula so it equals zero !! |
| What is the solution of a quatric formula ? | when yis made zero the solution becomes the x intercepts |
| What happens when you ha a x2 and a b x value but no c value >? | The constant ternm is is equal to square of one half of the number in fron of the x value. |
