The population of a country is decreasing, and its population (in millions) over six years is shown in the table. find an exponential regression curve to model this situation. a) y = 54.3(.918x) b) y = 67.2(.887x) c) y = 72.8(.842x) d) y = 83.9(.903x)

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
