Atrucker had a load of grain containing 2 tons. she unloaded 1 ton and 1,200 pounds at the warehouse. how much grain does she still have left on the truck?

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
