How can you tell if an exponential function is growth or decay just by looking at the function/equation? Give an example of growth and decay. y=_____•(_____)x a b Does h2co have hydrogen bonding
This example is about exponential growth. You are asked to solve for the increase in the population of a group of fruit flies given the growth factor. The example says their population started out at 40 fruit flies and triples every two days. The first step is identifying the unknown variables and assigning values to them.

Concept Summary: Functions defined by y = abx, where a is the initial value and b is the growth or decay factor are exponential functions. Y-intercept is (0, a) Growth factor, b > 1, y-values are increasing. Decay factor, 0 < b < 1, y-values are decreasing. Doubling time is the time for the y-value to double.
Section 7.1 Exponential Growth and Decay Functions 349 Graphing Exponential Growth and Decay Functions Tell whether each function represents exponential growth or exponential decay. Then graph the function. a. y = 2x b. y = ( — 1 2) x SOLUTION a. Step 1 Identify the value of the base. The base, 2, is greater than 1, so the function represents ...

1Exponential Function An exponential growth or decay function is a function that grows or shrinks at a constant percent growth rate. Try it Now 1. Given the three statements below, identify which represent exponential functions. A. The cost of living allowance for state employees increases...Exponential growth can be amazing! The idea: something always grows in relation to its current value, such as always doubling. Example: If a population of rabbits doubles every month, we would have 2, then 4, then 8, 16, 32, 64, 128, 256, etc! Lenovo celular z5sMath 1050 Project – Exponential Growth page 4 6. Using complete sentences briefly compare the three semi-log graphs (=2 ,˛ =3 , and =1.5 ). Exponential functions, when graphed on semi-log paper, are straight lines. We can also see this transformation algebraically. 7. Consider the function =3 . Hello! Exponential growth function has a form `y=A*(1+r)^x,` where A is the initial value and r is the growth rate. If we substitute x=0 we obtain `y(0)=A*(1+r)^0=A.` Recall that y-intercept is ... Narrator chp
