The statement that is true is the third statement - The domain of the graph is all real numbers less than or equal to 0
<h3>Domain and Range of a Function</h3>
From the question, we are to determine the statement that is true about the given function.
The domain of a function consists of all the input values shown on the x-axis.
and
The range is the set of possible output values, which are shown on the y-axis
The given function is
f(x) = √-x
The possible input values for the given function is the set of all real numbers less than or equal to zero. That is, the domain of the function is the set of all real numbers less than or equal to zero.
The possible output value for the given function is the set of all real numbers greater than or equal to zero. That is, the range of the function is the set of all real numbers greater than or equal to zero.
Hence, the correct statement is the third statement - The domain of the graph is all real numbers less than or equal to 0

So, from 10 minutes down to 2 minutes, the difference is 8 minutes.
if we take 10 to be the 100%, what is 8 off of it in percentage?
Answer:
x = theta = 0°
Step-by-step explanation:
Given the trigonometry function
Tan²x/2-2 cos x = 1
Tan²x-4cosx = 2 ... 1
From trigonometry identity
Sec²x = tan²x+1
tan²x = sec²x-1 ... 2
Substituting 2 into 1, we have:
sec²x-1 -4cosx = 2
Note that secx = 1/cosx
1/cos²x - 1 - 4cosx = 2
Let cosx. = P
1/P² - 1 - 4P = 2
1-P²-4P³ = 2P²
4P³+2P²+P²-1 = 0
4P³+3P² = 1
P²(4P+3) = 1
P² = 1 and 4P+3 = 1
P = ±1 and P = -3/4
Since cosx = P
If P = 1
Cosx = 1
x = arccos1
x = 0°
If x = -1
cosx = -1
x = arccos(-1)
x = 180°
Since our angle must be between 0 and 1 therefore x = 0°
