If b 1 the function represents exponential growth. It can be expressed by the formula ya1-bx wherein y is the final amount a is the original amount b is the decay factor and x is the amount of time that has passed. The rate of decay is great at first.
The exponent p is a non-zero number and the exponents decrease until the final exponent is zero.
In such cases I find it best to start plotting the graphs on the graph paper one by one. Large f x A e -kx f x Aekx. It began at a length of 6 in and grew at a rate of 14 a week. It can be expressed by the formula ya 1-bx wherein y is the final amount a is the original amount b is the decay factor and x is the amount of time that has passed.
