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

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

the general form of exponential function is .

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 .

where x is decreasing in decay function.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
