Question

How can you tell whether an exponential equation models growth or decay? Use the general form of an exponential expression to explain your answer.

Answer 1

ok we know that exponential functions have exponent at the top the funtions.

the general form of exponential function is $f(x)=y=a^x$.

we know that x is the exponent here.

if we have positive value of x .

we can say that exponential function is increasing or growth function.

if we have negative value of x it is decreasing or decay.

exponential function for decay is $f(x)=y=a^-x$.

where x is decreasing in decay function.

Answer 2

Answer:

If b > 1, the equation models exponential growth. If 0 < b < 1, the equation models exponential decay.
