f is a function that takes a real number x and performs the following three steps in the order given: (1) take the square root; (2) subtract 13; (3) make the quantity the denominator of a fraction with numerator 4.

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:

f is a function that takes a real number x : f (x)

(1) take the square root: f (x) = √x

(2) subtract 13 : f (x) = √x-13

(3) make the quantity the denominator of a fraction with numerator 4.

f (x) = 4 / (√x-13)

In conclusion, the expression for f (x) is ⇒f (x) = 4 / (√x-13)
