F(x)=3x^2 - 2x +1 
f(-1)=3(-1)^2-2(-1)+1 
f(-1)=3( 1 ) +2+1 
f(-1)=3+3 
f(-1)=6
        
             
        
        
        
6. 5 shirts  20 minutes Multiply both by 3 to get to 60 minutes
15 shirts  60 minutes
15 shirts per hour 
7. 250 miles + 50 miles = 300 miles
300 miles / 5 hours = 60 miles per hour
8. 360 pages / 12 hours = 30 pages per hour400 pages / 30 pages per hour = 13 1/3 hours
= 13 hours and 20 minutes
