The form of the linear function is
[tex]f(x)=ax+b[/tex]
a is the rate of change
b is the initial amount
In the given function
[tex]f(x)=1000-200x[/tex]
Compare it by the form of the linear function above to find a and b
a = -200
b = 1000
Since b is the initial amount, then
The account began with $1000
The true statement is A
