### How is it possible to graph a negative square root function ...

You can graph a negative square root function either by y = − x or y = − x You can graph the first equation on an x and a y axis because you just multiply the values of y = x by − can graph the second equation on a complex plane, with x being the real component, and y being the imaginary component of each value. 889 views

### Graphing square and cube root functions - Khan Academy

When you have an equation like f (x)=sqrt (-x), you use negative x-values because if you take the negative of a negative it becomes r example: f (-4)=sqrt (- (-4))=sqrt (+4)=erefore, when you input negative 4 into this function, the output is the square root of positive 4.

### Negative Square Root: Definition & Overview - Video & Lesson ...

As shown earlier, a negative square root is one of two square roots of a positive r the number 25, its negative square root is -5 because (-5)^2 = 25. We can solve certain equations by ...

### Which is the graph of the function f(x)= negative square root ...

First, note that is always positive (except for x=0), so must be always us, the only plausible graphs are 1 and 3 since they are below the x-w, and are only defined for x≥0, because only for these x'es we can take the square te that the third graph has domain (-infinity, 0], so it is not the right one, while 1 is ok.

### Graphing Square Roots of Functions |

Domain and range of a basic square root function are restricted, because the square root of a negative number does not th domain and range of the basic function are from zero to infinity. 3.

### Graphing Radical Functions | Purplemath

I know that I can't graph a negative inside a square root, so I need to nail down what x-values are going to be okay. I know, for instance, that x is not allowed to be 5 , because: To find the domain of this function, I take whatever is inside the radical (that is, I take the "argument" of the radical), and I set it "equal to or greater than zero".
