Without graphing, determine whether the function represents exponential growth or exponential decay. Then find the y-intercept.
f(x) = 3(0.69)*

Step-by-step explanation:

In the exponential growth/decay function,

, a is the intial amount and b is the decay or growth rate.  As a general rule, if b is greater than 1, the equation is growth; if b is greater than 0 but less than 1, the equation is decay.

Our b value is a decimal portion of 1, so our equation is decay.

The y-intercept of any function exists where x = 0.  If we plug in 0 for x and solve for y:

we get that

y = 3
