your first part is correct
for the 2nd part, I would have it as
T(x) = .0175x - 3000 , x ≥ 400,000
(so I have taken 1.75% on the whole thing, but then subtracted the 0.75% part for the first 400,000 which is 3000.
Where did you get your $500 from ? )
A certain state taxes the first $400,000 in property value at a rate of 1%; all value over $400,000 is taxed at 1.75%. Find a piecewise-defined function T that specifies the total tax on a property valued at x dollars. (Simplify your answer completely.)
0.01x if 0<x<400,000
T(x)= 0.0175x-500 if x>400,000
are my numbers right? (By the way the greater/less than signs are equal to as well)
