<em>Greetings from Brasil... </em>
For the composite function FоG(X) = F(G(X)), just replace the function G(X) in the X of F(X):
F(X) = X + 4
G(X) = 3X² - 7
F(X) = X + 4
F(G(X)) = [G(X)] + 4
F(G(X)) = [3X² - 7] + 4
F(G(X)) = 3X² - 7 + 4
<h2>F(G(X)) = 3X² - 3</h2>
Answer:
Part 5) Option b
Part 6) Option d.
Step-by-step explanation:
Part 5) we know that
The area of a square is equal to
where
b is the length side of the square
we have
substitute
Solve for b
take square root both sides
Remember that
substitute
Applying property of exponents
Part 6) we know that
The volume of a cube is equal to
where
b is the length side of the cube
we have
substitute
Solve for b
take cubic root both sides
Remember that
substitute
Applying property of exponents
Answer:
-37.
Step-by-step explanation:
a2 = 2 a2-1 - 3
= 2 a1 - 3
= 2*-2 -3
= -7
a3 = 2 a3 - 3
= 2*-7 - 3
= -17
4th term a4
= 2*-17 - 3
= -37.
Your answer will be negative 3
