Question 1112253: 7. Evaluate the function below over the domain {-1, 0,
1, 2}. As the values of the domain increase, do the
values of the function increase or decrease?
y = (3/4)ˣ
8. Suppose an investment of $5,000 doubles every 12
years. How much is the investment worth after 36
years? After 48 years?
Write and solve an exponential equation.
9. Does the function represent exponential growth or
exponential decay? Identify the growth or decay
factor.
= 9 ∙ (1/2)ˣ

You can put this solution on YOUR website! 7. Evaluate the function below over the domain {-1, 0,
1, 2}. As the values of the domain increase, do the
values of the function increase or decrease?
y = (3/4)ˣ = (3/4)(3/4)(3/4)^x
Since your always multiplying by 3/4, y decreases as x increases.
-----------------------
8. Suppose an investment of $5,000 doubles every 12
years. How much is the investment worth after 36
years? After 48 years?
Write and solve an exponential equation.
y = 5000*2^x
-------------------
9. Does the function represent exponential growth or
exponential decay? Identify the growth or decay
factor.
y = 9 ∙ (1/2)ˣ
Ans: decay ; 1/2
