Eva works for the Internal Revenue Service (IRS) and was asked to write a piecewise function for the 2021 Social Security tax function. She was provided the following information from the 2021 Social Security tax table before there was a separate Medicare tax:
Social Security: 6.2%
Maximum Taxable Income for Social Security: $135,600
Medicare: 1.45%
Maximum Taxable Income for Medicare (S): All income
Eva labels the x-axis 'Income ($ and the y-axis 'Social Security Tax ($). When Eva graphs the piecewise function, what will be the coordinate of the cusp?
