1. interquartile range
2. all
It's B.
You can think of the action of multiplying matrix <em>A</em> onto any other matrix <em>X</em> as
• preserving the first row of <em>X</em> due to the +1 in the first column of the first row,
• negating the second row of <em>X</em> due to the -1 in the second column of the second row, and
• preserving the third row of <em>X</em> due to the +1 in the third column of the third row.
Answer:
All real numbers
Step-by-step explanation:
Assuming the polynomial is
Then the domain is all real numbers.
The domain are all values of x, for which the given function is defined.
The reason is that, polynomials are defined everywhere on the real number line.
We can write this as {x|x is all real numbers} .
Or (-∞,+∞)
Answer:
- parent: y = x²
- transformed: y = -3x² +4
Step-by-step explanation:
You have correctly recognized that the function is quadratic, so has parent function y = x².
__
You may notice that the function drops by 3 units when x increases or decreases by 1 unit from the vertex. That factor (-3) is the vertical scale factor in the transformed function ...
f(x) = a(x -h)² +k
where "a" is the vertical scale factor and (h, k) is the location of the vertex of the transformed function.
We note that the graphed function has its vertex at (h, k) = (0, 4), so the complete transformed function with a=-3, h=0, k=4 is ...
f(x) = -3x² +4
Answer:
20 Edges
Step-by-step explanation:
As this figure shows only 10 edges..so to meet the given condition (8 faces; 4 hexagons & 4 triangles) same figure is present at the back making total of 20 Edges.
