Which function can be used to model the graphed geometric sequence? f(x 1) = five-sixthsf(x) f(x 1) = six-fifthsf(x) f(x 1) = five-sixths superscript f (x) f(x 1) = six-fifths superscript f (x)

Respuesta :

The function that can be used to model the graphed geometric sequence is y = 1555.2(5/6)^x

Exponential functions

The standard exponential function is expressed as y = ab^x

Using the coordinates (3, 900) and (4, 750)

Create the equations

900 = ab^3 ............. 1

750 = ab^4 ................. 2

Divide

900/750 = 1/b
b = 75/90
b = 5/6

Determine the value of "a"

900 = a(5/6)^3

900 = (125/216)a

a = 1555.2

Determine the required equation

y = 1555.2(5/6)^x

Hence the function that can be used to model the graphed geometric sequence is y = 1555.2(5/6)^x
