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>
Answer:
y = 3x - 2
Step-by-step explanation:
See Image for all the rest of the equation forms
1. -3x and -6x
2. 21 and -13
3. 21 and -13
4. -10b and 6b, 15 and -5
5. -20 and 30, 4c and -2c
The second equation has 4x in it t. So to eliminate X, you need to multiply y = x-2 by -4, so the x would become -4x.
It will take 30 more minutes to fill up the pool completely.
2/3 of the pool has been filled in 1 hour. This equates to 60 minutes. This means that in 30 minutes, 1/3 of the pool has been filled. Another 30 minutes and 2/3 of the pool has been filled.
Finally, another 30 minutes will mean that the whole pool is filled.
