The square root of a negative number such as -144 is undefined. explain why the square root of -x is not necessarily undefined know what this means about the domain and range of f(x) equals the square root of -x

Sample Response

Step-by-step explanation:

If x is a negative number, then negative x is a positive number and the square root can be determined. Therefore, the domain of the function is x ≤ 0.  As a result, the range is never negative either, so it is y ≥0.

Step-by-step explanation:

When x is a negative number, negative x is a positive number and it is possible to calculate the square root. Therefore, the function's domain is x distance 0. The scope is therefore never negative either, so it's y 0

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
