Answer:
Function: y = 1/6^x
Step-by-step explanation:
The function y = 1/6^x would be decaying faster because the function y = 2/3^x equals 4/6^x and that is 4 times greater than 1/6. That means that more of the value will be retained in the function y = 2/3^x or y = 4/6^x.

Answer:

Step-by-step explanation:
Apply Distributive property:

Add like terms and then add 63 to both sides of the equation:

Pick the coefficient of the x term, divide it by 2 and square it:

Add it to both sides of the equation:

Rewriting the left side as a squared binomial, we get:

Apply square root to both sides:

And finally we need to add 1 to both sides of the equation. Then we get:
