Answer:Solving the quadratic equation, the coordinates of the roots are: (-1,0) and (-3,0)
The quadratic equation given is:
Which has coefficients .
Now, we find the solutions:
The coordinates of the roots are and , as a root is a value of x when y = 0, thus, in the problem, (-1,0) and (-3,0).

Answer:
-45, 1, 4, 5, 9
Explanation:
The first argument value, -5, is less than -1, so the first section of the function definition is used. f(-5) = 9(-5) = -45.
The 2nd to 5th argument values are in the interval [-1, 3], so the second section of the function definition is used.
The last argument value, 6, is greater than 3, so the last section of the function definition is used. f(6) = (6 -3)^2 = 9.
Function values are shown in the table attached.
Answer:
Velocity
Explanation:
Speed is how fast something moves.
Velocity is how fast it moves and in what direction it moves in.
Acceleration is the change in how fast it moves. I.e. if it speed up or slows down.
Here we are given the speed of the train (75mph) and the direction (north), therefore it is velocity.
Hope this helped!
