You will have to figure out the last equation but here is the rest:
Answer:
f(x) x^3 - 2x^2 + 5x + 12
Step-by-step explanation:
Next time please share the goal. I'm guessing your intent was to multiply out the given function.
f(x) = (x^2 + x - 3x - 3)(x - 4), or
= (x^2 - 2x - 3)(x - 4)
Now apply the distributive property of multiplication:
f(x) = x^3 - 4x^2 - 2x^2 + 8x - 3x + 12, or
= x^3 - x^2(4 - 2) + x(5) + 12, or
f(x) x^3 - 2x^2 + 5x + 12
For the book store, it is a discreet graph. Every book is a case by itself, no event is dependent on the other. So now variable is dependent on another.
The swimming pool case, the time is the independent variable in the function where the water volume changes with respect to time. So it it has a continuous graph.
Hope this helps.
Answer:
TQ = 83.5
Step-by-step explanation:
11/54 = 17/TQ
11TQ = 918
TQ = 918/11 = 83.45
