Answer:
The best is f(x) = (x + 3)(x − 3)(x + 1).
Step-by-step explanation:
The coefficient of x^3 will be positive because of where the graph rises and falls.
As one of the x intercepts is negative 3 one of the factors will be (x + 3).
By the same reasoning the other 2 factors will be (x - 3) and (x + 1).
Here's what you have to do: multiply. 54.9×12= 658.8. So, he traveled 658.8 miles in twelve hours.
Is there answer choice options?
Answer:
(-4, -7) (-3, 5) (1, 3) (9, 19)
Step-by-step explanation:
Plug in the values of x (the domain numbers) into the equation to solve for the range values (y)
For example, for the x value of -4
y= 2(-4)+1
y= -8+1
y= -7
