Answer:
B. 4
Step-by-step explanation:
(g o f)(x) means that we put the expression for f(x) in for x in g(x):
(g o f)(x) = g(f(x)) = (x - 2)²
We want to find (g o f)(4), so plug 4 in for x:
(g o f)(x) = (4 - 2)² = 2² = 4
The answer is thus B.

Answer:
b=2
Step-by-step explanation:
Get rid of the parenthesis using distributive property:
6b+12+12b+6=54
Simplify
18b+18=54
subtract 18 from both sides
18b=36
divide by 18 on both sides
b=2
Answer:
y = 4x - 8
Step-by-step explanation:
x = 1/4y + 2
-1/4y -1/4y
-1/4y + x = 2
-x -x
-1/4y= -x + 2
*-4 *-4
y = 4x - 8
