If the multiplicity is even, the x-intercept will touch the x-axis and turn away (sometimes people call this "kissing" the x-axis). If the multiplicity is odd, the intercept will go right through the x-axis, so the answer to your question is false. In general, remember that odd crosses and even touches/turns/kisses.
 
        
             
        
        
        
One mile equals 5,280 feet, therefore you would multiply 12 x 5,280 which is 63360 feet per hour.
