<u>End behavior: </u>
The parent function is: f(x) = x³, which starts (from the left side) at -∞ and ends (on the right side) at +∞.
<u>Zeroes:</u>
f(x) = x³ + 2x² - 8x
0 = x³ + 2x² - 8x
0 = x(x² + 2x - 8)
0 = x(x + 4)(x - 2)
0 = x 0 = x + 4 0 = x - 2
x = 0 x = -4 x = 2
<u>Intervals:</u>
Put the zeroes in order: -4, 0, 2
since f(x) is increasing from the left then the interval from -4 to 0 is positive and the interval from 0 to 2 is negative.

Answer:
(a) 
(b) 
(c) 
(d) 
Step-by-step explanation:
We need to simplify the given expressions.
(a)
Consider the given expression is

Using the property of exponent, we get
![[\because a^ma^n=a^{m+n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5Ema%5En%3Da%5E%7Bm%2Bn%7D%5D)

(b)
Consider the given expression is

Using the property of exponent, we get
![[\because (a^m)^n=a^{mn}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%5Em%29%5En%3Da%5E%7Bmn%7D%5D)

(c)
Consider the given expression is

Using the property of exponent, we get
![[\because a^{-n}=\dfrac{1}{a^n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E%7B-n%7D%3D%5Cdfrac%7B1%7D%7Ba%5En%7D%5D)

(d)
Consider the given expression is

Using the property of exponent, we get
![[\because \dfrac{a^m}{a^n}=a^{m-n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cdfrac%7Ba%5Em%7D%7Ba%5En%7D%3Da%5E%7Bm-n%7D%5D)

The probability of pulling an ace is 4 out of 32 or 4/32. There are four aces in a complete set of playing cards. If you need me to simplify, it would be 1 out of 8, or 1/8. I hope this is helpful!
Among the choices given, the sentence which explains a clearer insight about precise measurement is the last one. The answer to this question would be;
<span>6 hours, because an hour is a smaller unit of measure than a day.
>> From the word itself "precise" meaning, accurate, only the last sentence of the the four sentences explains accurately regarding hour as a smaller unit than a day.</span>
