Substitute the value of x = 3 to the equation of the function:

f(x) = 2x² - x → f(3) = 2(3²) - 3 = 2(9) - 3 = 18 - 3 = 15

If you would like to know the production rate of factory E, you can calculate this using the following steps:

Factory   Number of days   Number of shirts
A             2                            600
B             3                            900
C             4                            1200
D             5                            1500

Factory E can make shirts at the same rate as the first four factories:
600 shirts / 2 days = 300 shirts per day
900 shirts / 3 days = 300 shirts per day
1200 shirts / 4 days = 300 shirts per day
1500 shirts / 5 days = 300 shirts per day

Factory E will make 1800 shirts in 6 days, therefore 1800 / 6 = 300 shirts per day.

The correct result would be:
Factory   Number of days   Number of shirts
E             6                            1800
