Answer: f(x) = 4 / (√x-13)
Step-by-step explanation:
Hi, the question is missing this part:
Find an expression for f(x)
To write the expression we have to analyze the information given:
<em>f is a function that takes a real number x</em> : f(x)
<em>(1) take the square root:</em> f(x) = √x
<em>(2) subtract 13 </em>: f(x) = √x-13
<em>(3) make the quantity the denominator of a fraction with numerator 4.</em>
f(x) = 4 / (√x-13)
In conclusion, the expression for f(x) is ⇒f(x) = 4 / (√x-13)

It will be the beaut in the the the the the. The the the good day onto the hair or in to the bob
First, put the whole fractions to mixed fractions.
First Fraction
4*3+1= 13
Always keep the denominator the same when putting whole to mixed fractions.
13/4
Second Fraction
10*1+1=11
11/10
13/4+11/10
Now, we need both denominators the same number.
13/4*5/5 =65/20
11/10*2/2=22/20
Now we have the denominators the same. We can proceed to add.
65/20+22/20= 87/20
That is the answer for mixed fraction. There is another one for WHOLE fraction.
87/20 =
![4 \times \frac{7}{20}](https://tex.z-dn.net/?f=4%20%5Ctimes%20%5Cfrac%7B7%7D%7B20%7D%20)
"4" 7/20
