Question

f(x) = 32g(x) = V48xFind (f.g)(x). Assume x20.O A. (f.g)(x) = 72.O B. (f.g)(x) = V51xO c. (f.g)(x) = 12/xO D. (fºg)(x) = 12xSUBMIT

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

f(x) = √3x

g(x) = √48x

(f . g)(x) = ?

Step 02:

(f . g)(x) :

`\text{ (f.g)(x) = }\sqrt[]{3(\sqrt[]{48x)}}`
`(f.g)(x)\text{ = }\sqrt[]{3(48x)^{(1)/(2)}}\text{ }`

(f.g)(x) = 12 √ x

The answer is:

(f.g)(x) = 12 √ x
