Question

Consider functions f and g.
f(x) = 3/x + 1
What is the value of f(g(1))
A. 9
B. 3/2+1
C. 0
D. 1​

Answer 1

Answer:

D. 1

Step-by-step explanation:

You are given the values of x that correspond to g(x).

Then you are given f(g(1)), the function of f, the function of g(x) at 1.

When x is 1, g(x) is 0.

f(x) is 3 times the square root of x plus 1.

Since x is now 0, three times the square root of 0 is still zero. The one remains.

Answer 2

   Given function → $f(x)=3\sqrt{x} +1$

In the picture attached, for every value of 'x', value of function 'g' has been given.

For x = 1, g(1) = 0

Now substitute the value of g(1) in function 'f',

$f(g(1))=f(0)$

Since, $f(x)=3\sqrt{x} +1$

Therefore, $f(0)=3\sqrt{0}+1$

                         $=1$

    Hence, Option D will be the correct option.
