Means the number you can use
remember we can't divide by zero
domain is x^2-9
set to zero to find values we can't use
x^2-9=0
x^2=9
x=+/-3
domain=all real numbers except -3 and 3
Answer:
A. horizontal reflection
Step-by-step explanation:
Given:
To identify the type of transformation.
Solution:
On close observation of the functions we find the that sign of 
has changed in 
with other terms being constant.
<em>Thus, the transformation statement can be given as:</em>
As:
The transformation describes horizontal reflection of function across the y-axis.
Thus, 
is horizontally reflected across y-axis to get .
4a+3b-(-2a-3b)
=4a+3b+2a+3b
=6a+6b
=6(a+b)
A because if you subtract 56 from both sides, then x would show you what equals the tied record
Yes. Changing the the word problem into a function, you get 30x=y.
30 = Fixed Length
x = width
y = area
No matter what width (x) you choose, the area (y) is going to be a multiple of 30 (the fixed length) because with two numbers being multiplied, if there is a fixed number that will always be the multiple and not the multiplier. For example, 10 multiplied by every number 1-10 is going to be a multiple of 10.
10x1=10, 10x2=20, 10x3=30, etc
So if Tom chooses any of these widths (x) 5, 10, or 15, y (the area) will be a multiple of 30.
30(5)=150
30(10)=300
30(15)=450
So as we double 5 to get 10, our outcome is doubled 150 to 300 and so forth. Hope this helps.
