The initial number of bacteria in a culture was 12,000. The culture doubled each day. What is the y-intercept and asymptote of the graph representing this exponential function?

y-intercept: $$\left(0,\ 12000\right)$$

y-intercept: $$\left(12000,0\right)$$

In 2015, a city had a population of 120,000 people. The population has been declining at a rate of 3% each year since 2015. What is the y-intercept and asymptote of the graph representing this exponential function?

y-intercept: $$\left(0,120000\right)$$

y-intercept: $$\left(120000,\ 0\right)$$

Given the function f(x) = 1.07 x , how do you know this is an exponential function?

Because the variable is in the exponent

Because the base has a decimal in it

Given the function f(x) = 1.07 x , how do you know the exponential function shows growth or decay?

Growth or decay is determined by the value of the base

Growth or decay is determined by the value of the exponent

Because exponential functions are always growth functions

Because exponential functions are always decay functions
