<span>g(x) = x3
– x2 – 4x + 4 </span>
<span>You can find
the zeroes by factoring the equation. x<span>2 </span>(x - 1) - 4(x - 1) = 0 </span>
<span>(x2
- 4) (x - 1) = 0 </span>
(x + 2) (x -
2) (x - 1) = 0
x = 2, -2,
and 1
The
following are the key features of g(x):
g'(x) yields
the slope
g''(x) yields
the concavity
g'(x) = 0 provides
the critical points
<span>g''(x) = 0 provides the point of inflection</span>
There are 9 number cards from 2 to 10 in a deck of cards.
(2-10) has one 9
(2-10) has one 9
(2-10) has one 9
(2-10) has one 9
There are 4 nines in a deck of 52 cards. We know that 4 x 9 = 36.
The chance or probability of taking out a 9 is (36/52).
Reducing this fraction to the lowest terms we get 9/13.
A ratio reads left to right and can be written in 3 different ways. for example, 3:5, 3 to 5, or 3/5
if you have a problem that says something like: for every 3 people there is 1 child, the ratio is 3 to 1. Hope this was helpful in in 6th grade too and in advanced math!
The answer is a² + 6. "Sum of a squared and 6" means you square a value and then add 6 to it.
