The value of the composite function fog(1) is -1
Step-by-step explanation:
Step 1 :
Given,
f(-2) = -1
g(1) = -2
We need to find (fog)(1)
Step 2 :
Function f(2) means the value of the function f when x = 2
fog refers to composite function f(g(x)), that is evaluate the function g for x and then evaluate the function f for the result
So to find the composite function (fog)(1) we need to find g(1) first and then apply the function f on the result.
so g(1) = -2
f(g(1))=f(-2) = -1
fog(1) = -1
Step 3 :
Answer :
The value of the composite function is -1
You can take x = a, 2y = b and then can apply the binomial theorem.
The expansion of given expression is given by:
Option D: is
<h3>What is binomial theorem?</h3>
It provides algebraic expansion of exponentiated(integer) binomial.
According to binomial theorem,
<h3>How to use binomial theorem for given expression?</h3>
Taking a = x, and b =2y, we have n = 7, thus:
Thus, Option D: is correct.
