Two combine harvesters are able to harvest the crop from 320 acres in a certain amount of time. working together for the same time, how many acres can be harvested by: 3,4 and 12. combine-harvesters will mark brainliest!

2=320

320/2=  160

Key:

*1=160

3*160=480

4*160=640

12*160= 1920

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .

step-by-step explanation:

mark brainliest.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
