Question

The value of an investment of $3,500 over t years at 4.5% interest is represented by the expression 3500(1.045)t. Which kind of expression is 3500(1.045)t? exponential decay exponential growth quadratic linear

a: exponential decay
b: exponential growth
c: quadratic
d: linear

Answer 1

It's B

Explanation:

I took the Test.

Answer 2

b) exponential growth

Explanation:

The value of an investment of $3,500 over "t" years at 4.5% interest is represented by the expression

`3500(1.045)^(t)`

The general form of exponential expresion y = a.
`b^(x)`

If exponent "x" is positive, then it is exponential growth. If exponent "x" is negative, then it is exponential decay.

Our given expression is in the form of exponent. Here the exponent "t" represents the number of years. It must be positive.

Therefore, our given expression is b. exponential growth.

Hope you will understand the concept.

Thank you.
