Answer:
Option B.
Step-by-step explanation:
The given table of values is
x f(x)
-3 -2
-2 0
-1 2
0 2
1 0
2 -8
3 -10
4 -20
We need to find the interval for which the function f(x) is positive.
From the given table it is clear that the value of function f(x) is negative before -2 and after 1.
The function positive between x=-2 and x=1. So, we can conclude that the function f(x) is positive for the interval (-2,1).
Therefore, he correct option is B.
0.9 = 90%.
<span>0.9 in percent
= 0.9 x 100%
= 90%</span>
3.2 * 10^-4 = 0.00032
So the number is less than 1.
The effect the negative exponent has is.....well...here's an example
if the exponent was a positive it would be 3.2 *10^4 = 32,000
If it was positive you would move the decimal point to the right (for this equation) 4 times... if it was negative you would move it the other way.
I believe it’s c/100.
2=20
10 divided by 2 = 5.
Multiply 5 by 20. That equals 100.
