Question

what is the approximate erence between the growthSacro = 22/1 12)* and the growth factor of theexponential function that is the values in the table below?

Answer 1

ANSWER

b. y = 5·(0.52)^x

EXPLANATION

In the graph we can see that when x = 0, the function is 5 - this is the y-intercept. Therefore, the coefficient must be 5, so it's either a or b.

Then, the growth/decay factor must be less than 1, because it's a decay as seen in the graph. Therefore, the correct function is option b:

$y=5(0.52)^x$
