Answer:
<h2>0</h2>
Step-by-step explanation:
METHOD 1.
We know:

Therefore

METHOD 2.


exchange x to y and vice versa:

solve for y:
<em> subtract 12 from both sides</em>
<em>divide both sides by 3</em>

replace x in f(x) with the expression

put x = 0 to 

METHOD 3.


Calculate the value of <em>f</em> ⁻¹(x) for x = 0:

Calculate the value of <em>f(x)</em> for x = -4:

Answer:
yes,
Step-by-step explanation:
For example, if it lands on 4, then u do 1*2*2*2*2 because it is 4, if 5, then do 1 *2*2*2*2*2, the two will change according to the hours.
Answer:
√4x + 3 - √4x - 1 = 2
√4x + 3 = 2 + √4x - 1
(√4x + 3)² = (2 + √4x - 1)²
4x + 3 = 4 + 4√(4x - 1) + 4x - 1
4x - 4x + 3 + 1 - 4 = 4√4x - 1
o = 4√4x - 1
√4x - 1 = 0
4x - 1 = 0
4x = 1
x = 1/4
