In March 2020, before the Covid-19 lockdown, 1200000 Texans had applied for unemployment. During Covid-19 lockdown, the number of people applying for unemployment increased by 4% each month. Which exponential function can be used to find the number of people applying for employment after x months of covid-19 lockdown?

• y = 1200000(1.04)^x

• y = 1200000(0.4)^x

• y = 1200000(1.4)^x

• y = 1200000(0.06)^x

• y = 4(1200000)^x
