Find (f•g)(x) when f(x)=sqrt x+3/x and g(x)=sqrt x+3/2x
elena-14-01-66 [18.8K]
For multiplying radical expressions, we are first to list down the given.
  f(x) = (x + 3/x)^(1/2),   and
  g(x) = (x + 3/2x)^(1/2) 

We take a look at first the values of the radicands, these are the numbers inside the radical signs. Since, both of the radicands are raised to exponent 1/2, it is easy to say that we just have to multiply them and raise the product to the exponent 1/2 as well. That is,
 
(f·g)(x)  = ((x + 3/x)(x + 3/2x))^(1/2)

Simplifying,
(f·g)(x) = ((x² + 3/2 + 3 + 9/2x²)^(1/2))

Further simplification will lead us to the final answer of,
<em>(f·g)(x) = (x² + 9/2 + 9/2x²)^(1/2)</em>

Is tan^-1(a) equivalent to (tan(a))^-1? explain why or why not.
BARSIC [14]

Answer:

  No. The reciprocal of a function is rarely the same as the inverse of the function.

Step-by-step explanation:

tan^1(a) signifies the arctangent function, the function that returns the angle for a given tangent value of a.

tan(a)^-1 signifies the reciprocal of the tangent function, which is the definition of the cotangent function.

The attached graph compares the two functions.
