4x-3=5y
it would be : 4x - 5y = 3
The highest is 7 degrees and lowest is -8 so subtract and you get a difference of 15 degrees
Step-by-step explanation:
√a is defined only when a >= 0.
Therefore for √4x * √(x + 2) to be defined, both 4x and x + 2 must be non-negative.
When 4x >= 0, x >= 0.
When x + 2 >= 0, x >= -2.
x >= 0 and x >= -2, therefore we have x >= 0. (D)
