Answer:
Domain: all real numbers
Range: all real numbers
Step-by-step explanation:
I'm assuming you mean the function 
. That's usually written
f(x) = x^(1/5) with the ^ meaning "to the power of..." and the fraction exponent in parentheses so as not to be confused with x^1/5 which could mean x to the first power, divided by 5.
Fractional exponents are used to indicate roots. In this case, x is being raised to the 1/5 power, so this is the fifth root of x, written ![\sqrt[5]{x}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%7D)
. The 5 is called the root index.
For odd roots, like this one, the domain is all real numbers--<em>x</em> can be any number at all. So the domain is all real numbers.
The range is also all real numbers. Attached is a graph of this function. It might not look like it, but the graph rises to the right to any height. The larger <em>x</em> gets, the larger the 5th root gets. A similar thing happens on the left--the smaller <em>x</em> gets, the smaller the 5th root gets.
EDIT: see the comment. For the function 
, the domain is all real numbers. The range is positive real numbers. I'll attach a graph!
Answer:
4) About 96% of newborn girls were the same length as Alexandria.
Step-by-step explanation:
Given two points A and B, lines from them to center of the circle form the central angle∠<span>AOB. The central angle is the smaller of the two at the center. It does not mean the </span>reflex angle ∠<span>AOB. As you drag the points above, the angle will change to reflect this as it increases through 180°.
</span>Identify the inscribed angle<span> and </span>central angle<span> subtended by the same arc. </span>Recognize<span> that the </span>central angle<span> is twice the measure of the inscribed </span>angle<span> subtended by the same arc. Identify the tangent(s) to a</span>circle<span>. Identify the point of tangency on a </span><span>circle</span>
Answer:
The exponential function to model the duck population is:
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years
Step-by-step explanation:
In order to calculate the duck population you can use the formula to calculate future value:
FV=PV*(1+r)^n
FV=future value
PV=present value
r=rate
n=number of periods of time
In this case, the present value is the initial population of 415 and the rate is 32%. You can replace these values on the formula and the exponential function to model the duck population would be:
f(n)=415*(1+0.32)^n
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years
