Step-by-step explanation:
<u>According to given table we have pairs of points:</u>
- (4, 6.00), (5, 8.25), (6, 10.50)
<u>The rate of change is:</u>
- (8.25 - 6.00)/(5 - 4) = 2.25
or
- (10.50 - 8.25)/(6 - 5) = 2.25
<u>It is 2.25 and the meaning is:</u>
all the coordinates of the original triangle have been multiplied by 1/2
A (-4,-6) x 1/2 = -2,-3
B (-8,2) * 1/2 = -4,1
C (-2,4) *1/2 = -1,2
so the scale factor is 1/2
Answer is B
It states your "X" will be zero when solving for "Y".
So when solving for "Y" your equation would be;
0+y=4
Then you solve. Y=4
Then you do the same with the "X":
X+0=4. Then you solve. X=4
It would end up being (4(x),4(y) )
Then do the same for the next problem.

no...because it extends to infinity from one side
Answer:
y = -2(x - .5)^2 - 2.5
Step-by-step explanation:
You first want to find the vertex of the parabola, which is found at (.5, -2.5)
You then want to add this to the function "y = x"
y = (x - .5) - 2.5
You would then notice this would need to be a quadratic formula, so you would add the squared to the equation, and make the leading coefficient negative because it is facing downwards.
y = -(x - .5)^2 - 2.5
Finally, you would notice that the graph has a y-intercept of -3. You can Vertically stretch the equation y a factor of 2 to finish the graph.
y = -2(x - .5)^2 - 2.5
