Answer: 2.1 Find the Vertex of y = x2-17x-50
Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero).
Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.
Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.
For any parabola,Ax2+Bx+C,the x -coordinate of the vertex is given by -B/(2A) . In our case the x coordinate is 8.5000
Plugging into the parabola formula 8.5000 for x we can calculate the y -coordinate :
y = 1.0 * 8.50 * 8.50 - 17.0 * 8.50 - 50.0
or y = -122.250
Step-by-step explanation:
Answer:
The transformation that occurs from 
is compression by 3 units horizontally and shift of 4 units upwards.
Step-by-step explanation:
Given
Translation Rules:
If 
the function is compressed 
units horizontally.
If 
and 
the function stretches units horizontally.
If the function shifts units to the up.
If 
the function shifts units to the down.
Applying the rules to 
Step 1
[compressed 
units horizontally]
Step 2
∴
[shifts 4 nits up]
∴ The transformation that occurs from is compression by 3 units horizontally and shift of 4 units upwards.
If the result is neither negative nor positive, the simplest option is saying that 0 is neither negative nor positive.
For a number to be subtracted from it's square and equal 0, the only possible number is 1.
1 squared is 1, and 1-1=0.
