Scientists measure how much carbon is in something that died, and use the exponential function f (x) = (0.999879)x to figure out when it must have died. (The number 0.999879 is the base of this …

“Exponential growth” means that the function and its slope stay proportional. The time you give to that graph is well spent. Once formulas arrive, they tend to take over. The formulas are exactly right, and …

If the annual growth rate averaged about 1.3% per year, write an exponential equation that models this situation. Use your model to estimate the population for this year.

Transformations of exponential graphs behave similarly to those of other functions. Just as with other parent functions, we can apply the transformations to the parent function without loss of shape.

The exponential function, including its real- and complex-valued forms, constitutes one of the most important concepts in mathematics. In this work, the exponential function is approached in a …

Because the exponent is unrestricted, the domain of an exponential function is all real numbers (−∞,∞). To find the range of an exponential function we can use an input/output table like the one given below.

7. The function ex You have seen exponential functions such as y = 10x or y = 2x. These functions look like y = bx, where b is the base of the exponential function. In calculus, the most commonly used …
