4. In ballistics, the paths of projectiles are studied. It is known that the greater the speed at which an object is fired, the farther it will travel. For a particular spring-loaded cannon, this relationship can be modelled by d = 10 . where d is the distance, in metres, travelled by the projectile and v is the muzzle speed, in metres per second. a) Graph the distance function and state its domain and range. b) Graph the inverse of the distance function and state its domain and range. c) What does the inverse represent? a b ) 5. Use the Factor Theorem to determine whether or not the following are factors of the polynomial P(x)=x'+3x - 6x -8 a) x+1 b x - 3
