Answer:
Domain is all real Numbers
Range is all numbers over 0 - (0,
∞
)
Explanation:
One thing that you have to remember is that when you are finding the domain of a polynomial, it is all real number. it runs from
(
−
∞
,
∞
)
For finding the range, in a quadratic formula, you have to find when the finction has it's vertex. That is the place that the max or min happens and then you can find the range from there.
in this situaltion we found that the vertex is at the the origin at (0,0)
therefore the range is (0,
∞
)

Answer:
14
Step-by-step explanation:
So, if x is length, then x*x*8 is 1568. To solve, you do 1568/8, which gives you 196. The square root of 196 is 14, and 14*14*8 is 1568.
I would start like this: which year was the seventh AMC 8??
the first was in 1985
The second: 1986
3: 1987
4: 1988
5: 1989
6: 1990
7: 1991
so seventh AMC 8 took place in 1991.
she was then 12, so we can subtract this age from 1991:
1991-12=1979
so she was born in 1979!
