Find the indicated values, where
Rom4ik [11]

Answer:

option (b) is correct.

The value of g(f(3)-2f(1))  is 0.

Step-by-step explanation:

Given: g(t)=t^2-t and f(x)=1+x

We have to find the value of g(f(3)-2f(1))

Consider the given function f(x)=1+x

First evaluate value of function f(x) at x = 3 and 1 then substitute it in g(f(3)-2f(1)) .

f(3) = 1 + 3 = 4

f(1) = 1 + 1 = 2

Substitute, we get

g(f(3)-2f(1))=g(4-2(2))

Solving further , we get,

 g(f(3)-2f(1))=g(4-4)=g(0)

Now evaluate g(t)=t^2-t at t = 0 , we get,

g(0)=0^2-0=0-0=0

Thus, value of g(f(3)-2f(1))  is 0.

Thus, option (b) is correct.
