Question

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 1

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)
