Step-by-step explanation:

the change is 4.3-3.2=1.1 it is a decrease

from 2000 to 2005 the percentage(decrease)= 100*(3.2-4.3)/4.3=-25.60

for 2005 to 2010

=100 *(5.6-3.2)/3.2=75

it is an increase

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
