Question

Does the equation y = 5(2.3)* model exponential growth, exponential decay or neither?

Answer 1

It models exponential growth

Explanation:

Use the formula f(x)=a(1+r)^x where r is the growth rate, a is the principal value, and x is the length of time.

Since r would be equal to 2.3-1=1.3, this means a growth rate of 130%, which means the model models exponential growth since r>1.

Answer 2

Exponential growth because maths is good
