ANSWER

EXPLANATION
The given function is

Let us split the middle term to get,

We factor to obtain,


Let us find the zeros of f(x),

Either


We need to find the x-value of the vertex, which is the midpoint of the x-intercepts.
This gives us,

Hence the axis of symmetry of the parabola has equation,

Since the given function has minimum turning point, it will decrease and then increase.
The function will be increasing for

The function will be increasing and positive for
Answer:
40 miles per hour
Step-by-step explanation:
Driver a could be going 50 miles per hour
Driver c could be going 30 miles per hour
40 miles per hour is in the middle so that could be your answer
When he divided the gallon of paint into three containers, he put 1/3 a gallon of paint into each container.
Answer:
Equation of the parabola is 
Step-by-step explanation:
We have to find the equation of a parabola with vertex is (-4,-3) and a directrix x=2.
As vertex is (-4,-3) that means parabola is in third quadrant.
So the standard formula of the parabola will be y²= -4px through origin (0,0).
But when a parabola is shifted from origin to the left of y axis so the equation will be (y-shifting form y axis)² = -4(distance between vertex and directrix)(x-shifting from x axis)
