Tell whether the function represents exponential growth or exponential decay. Identify the percent increase or decrease. Then graph the function.
Find an equation in slope-intercept form of the line passing through
Tell whether the function represents exponential growth or exponential decay. Explain your reasoning.
Do the equations
Identify each function as exponential growth or decay, and find the growth or decay factor.
Radioactive substances decay exponentially. For example, a sample of Carbonwill lose half of its mass every 5730 years. (In other words, the half-life of is 5730 years.) Let A be the initial mass of the sample. Model the decay of using a discrete-time model... (1) using years. (2) using Δt=1year.
