f ( x ) = 6 * ( 1 / 2 )^x; Option C

Step-by-step explanation:

We can tell that this exponential model, modeled by 4 possible exponential function, could be only one of either types exponential growth, or exponential decay. As the graph decrease it should model exponential decay, in the form;

f ( x ) = a * ( b )^x, where a ⇒ start value, b ⇒ constant, and x ⇒ varies depending on situation,

Now if a ⇒ start value, we can tell that the y - intercept is ( 0, 6 ), which would mean that the equation so far is ⇒ f ( x ) = 6 * ( b )^x . b acts as a constant, a number with which two points known on the plot differ by the multiplication of it . We know for certain that the points ( 0, 6 ) and ( 1, 3 ) are points on the graph, and 6 and 3 differ by the multiplication of 2 . Thus we have before us the equation f ( x ) = 6 * ( 1 / 2 )^x;

Answer; f ( x ) = 6 * ( 1 / 2 )^x; Option C

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?
