The vertex form of the function is given by;
where is the vertex of the parabola.
We substitute a third point say, (3,5) to find the value of a;
The function is
The average rate of change for the interval x=5 to x=6 is
Answer:
(-7)(-1.2)=8.4
(7)(-1.2)=-8.4
(2.5)(-2)=-5
(-2 1/2)(2)=5
Step-by-step explanation:
First,a negative multiplied by another negative will have a product that is positive.
Also, -2 1/2 is the same as -2.5
Mentally, rotating the Cartesian Plane 180º, we find that the figure that was in the 4th quadrant goes to the 2nd quadrant.
So, answer B
Both solutions are x<span> = 2 and x = -2 are correct
because
</span>when x = 2 , |2| = 2
and
<span>when x = -2, |-2| = 2
