What is the exponential function that best models the number of gnats the scientists have
1 answer:
Answer:
(b) f(x) = 12.5(1.6^x)
Step-by-step explanation:
An exponential model is generally of the form ...
f(x) = a·b^x
where 'a' is the initial value (for x=0), and 'b' is the growth factor, the multiplier when x increases by 1.
<h3>Growth factor</h3>The ratio of the f(x) values for x=0 and x=1 is 20/12 ≈ 1.67. A number close to this will be the growth factor in the exponential function. There is only one answer choice showing a growth factor near 1.6. (Eliminates choices A, C, D.)
An exponential regression model can be produced by many graphing calculators and spreadsheets. The attachment shows a model that has the values matching choice B.

Answer:
Step-by-step explanation:
So I'm assuming when you typed "log yhat=.4785 + 1.468x", you meant to write: . And generally a logarithm can be written in the form
which can then be rewritten as
, but since the log has no base, it's assumed to be 10. So in this case you have the equation:
, which can then be written in exponential form as:
