The curve the order pairs (0,10) and (1,5) and (2,2.5) can be represented by the function f(x)=10(0.5)x what is the multiplicative rate of change if the functions

The multiplicative rate of change is 0.5.

Step-by-step explanation:

The given function is

              .... (1)

It is given that the curve is passing through (0,10), (1,5) and (2,2.5).

The exponential function is defined as

               .... (2)

Where, a is initial value and b is growth factor of multiplicative rate of change.

On comparing (1) and (2), we get

Therefore the multiplicative rate of change is 0.5.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
