10/12, 15/18, 20/24, 25/30, 30/36, ... and so on.
Answer:
x - f(x)
0 - 1
1 - 2
2 - 4
3 - 8
4 - 16
5 - 32
Step-by-step explanation:
Plug in the x values into the function 2^x.
<span>Simplifying
X2 + -4 = 0
Reorder the terms:
-4 + X2 = 0
Solving
-4 + X2 = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + X2 = 0 + 4
Combine like terms: -4 + 4 = 0
0 + X2 = 0 + 4
X2 = 0 + 4
Combine like terms: 0 + 4 = 4
X2 = 4
Simplifying
X2 = 4
Take the square root of each side:
X = {-2, 2}</span>
