Question

Two math students were asked to describe the exponential equation: y=230(0.98)^x

Answer 1

See below

Explanation:

Its an equation of decay because continuous multiplication by 0.98 decreases the value of the function as x increases. Its gradual slow decay because 0.98 is just below 1. The graph will pass through the point (0,230) ( when x = 0) and is continuous over the range of all real numbers. The graph is not a straight line but slightly curved.
