Answer:
a) Find the value of the function when x = -2
b) we get f(-2)=65
Step-by-step explanation:
We are given the function f(x)=6(8-x)+5
a) What does the notation f(-2) mean?
The notation f(-2) means that we have to put x = -2 in the given function of f(x) and find the value of the function when x = -2
b) What is the value of f(-2) ?
We need to find the value of f(-2)
Put x = -2
So, we get f(-2)=65
Answer:
Given functions,
Since, by the compositions of functions,
1. (g◦f)(x) = g(f(x))
Since, (g◦f) is defined,
If 3 - x² ≥ 0
⇒ 3 ≥ x²
⇒ -√3 ≤ x ≤ √3
Thus, Domain = [-√3, √3]
2. (f◦g)(x) = f(g(x))
Since, (g◦f) is defined,
If x ≥ 0
Thus, Domain = [0, ∞)
3. (f◦f)(x) = f(f(x))
Since, (f◦f) is a polynomial,
We know that,
A polynomial is defined for all real value of x,
Thus, Domain = (-∞, ∞)
