Answer: Formula= x^2 - 2x - 8
Roots=(-2 , 0) (4 , 0)
Step-by-step explanation:
1.) find the equation (the formula is Ax^2 + Bx + C, so plug it in)
2.)Plug it into your calculator's Y= X^2 - 2X - 8 (if you have one)
3.)Press 2nd, Calc, 2
4.)Go to the X Intersect , it will say Left Bound at the bottom left corner
5.)Press the left arrow about 3 or 4 times, hit enter
6.) It will now say Right Bound in the same corner go back to the X intersect, now press the right arrow 3 or 4 times
Repeat steps 3 to 6 for the other X intersect.
So if you want to find the answer you would find it by doing it yourself
<span>E = {x|x is a perfect square between 1 and 9} = {1,4
</span><span>F = {x|x is an even number greater than or equal to 2 and less than 9}
</span><span>D = {x|x is a whole number}
</span>
answer
D ∩ (E ∩ F) = 4
Answer:
x=12
Step-by-step explanation:
5(x-3)=45
x=12
if we take 6 to be the 100%, what is 8 off of it in percentage?
