A certain county has a tax code, where 10% tax is paid on all income up to the rst $10,000, a 15% tax is paid for any income over $10,000 and up to $15,000, and a tax rate of 25% is paid on all income over $25,000. Find a piecewise function to calculate the total tax T (x) on an income of x dollars. Solution.
In this lesson we’ll be covering how to set-up piecewise defined functions based on story problems. Keep in mind that each piece of a piecewise defined function has its own domain, so we’ll also have to set-up an interval for each piece, just like the sample piecewise function given below: :𝑥 ;= { 𝑥 ; 𝑥≤
Evaluate the function for the given value of x. Match the piecewise function with its graph. Write the answer next to the problem number.
