Answer:
isosceles
Step-by-step explanation:
A) The domain remains the same.
Since, in y = - 2 f(x) , the y is whats being multiplied and therefore changed, not the x or domain.
Therefore D[-6,10] <span>
The range is what changes by a factor of -2.
If the original range was [-8,12], then the new one is
[(-8 x -2),(12 x -2)] = [16 , -24].
However, you must flip the numbers to make the interval true, giving you R [-24,16]</span>
Q. Have you ever graphed functions?
A. Yes, yes I have, plenty of times.
Q. types of functions have you graphed?
A. Mostly linear and some quadratic and others.
Q. What methods have you used to graph functions?
A. By methods I think of equations or steps, correct me if I'm wrong or mistaken.
Y=mx+b for linear functions and more.... I'd use a input output chart.
I'd separate the domains and ranges, etc....
To solve this, first we'll find the area of the rectangle A,
Area=length × width
?=24m×20m
480m=24m×20m
480m squared=area of the rectangle A
now we'll find the width of rectangle B,
"the width of rectangle B is 12 meters less than the width of rectangle A",
20m-12m= 8m
8m=width of rectangle B
finally we'll find the length of rectangle B,
area of the rectangle B= 480msquared
width= 8m
length=? (to find this divide the area by the width)
480÷8=60m
length of the rectangle B=60m
