Which statement is true about the function f(x)=-√-x a. the domain of the function is all negative real numbers. b. the range of the function is all positive real numbers. c. the domain and range of the function have opposite signs. d. the domain and range of the function are the same.

D.The domain and range of the function are the same.

Step-by-step explanation: Given function f(x)=-√-x.

The given function is a square root function and we have minus sign in front of x inside square root.

A square root always defined for positive values or 0.

In order to get a positive number or 0 inside square root, let us solve the inequality:

On dividing both sides by -1, the inequality sign would get flip and we get

Domain:

We can see that we have a negative sign in front of square root. So, the value of f(x) would be always a negative number or 0.

Therefore, range would also be :.Therefore, correct option is D option.

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
