Answer: Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences.

DochEvi [55]

If A is the buying value & B the selling value, then the increase =

Increase = (B-A)/A = (1.15 - 0.87)/0.87 = 0.3218 or 31.18%

Which of the following would not be a possible function for f (x) and g(x) such that f of g of x is equal to 6 over the quantity

Aleonysh [2.5K]

Option C is correct. the functions that would not be a possible function for f (x) and g(x) are f(x) = $\frac{4}{x^2+2}$ and g(x) = x

Given the composite function

$f(g(x))=\frac{6}{x^2+3}$

We are to look for two functions f(x) and g(x) that will not give the same function

Using trial and error,

If f(x) = $\frac{4}{x^2+2}$ and g(x) = x

Determine the f(g(x)) for this function

f(g(x)) = f(x)

This is gotten by simply replacing x with x in f(x). This will return back the function f(x) making this the right choice.

f(g(x)) = $\frac{4}{x^2+2}$

Since, $\frac{4}{x^2+2}$ $\neq \frac{6}{x^2+3}$ , hence the functions that would not be a possible function for f (x) and g(x) are f(x) = $\frac{4}{x^2+2}$ and g(x) = x
