How do i check an equation for extraneous solutions?
Marina86 [1]
Example:

\sqrt x(x+1)=0

This suggests two solutions, x=0 and x=-1.

However, upon plugging these solutions back into the equation, you get

\sqrt0(0+1)=0(1)=0

which checks out, but

\sqrt{-1}(1-1)=0

does not because \sqrt x is defined only for x\ge0 (assuming you're looking for real solutions only). So, we call x=-1 an extraneous solution, and the complete solution set (over the real numbers) is x=0.

I’m really confused on this problem., pls help me!
777dan777 [17]

Answer:

Domain: All Real Numbers

Range: All Real Numbers

Step-by-step explanation:

So the domain of a function can be defined as an interval of x-values, which you can input into the function and get real numbers as an output. Since we have a cube root here, or more specifically an odd nth root, the domain is all real numbers, since cbrt(negative number) will just be a negative number since (negative number * negative number * negative number) = negative number, so there does exist a solution, unlike even nth roots like square root, which is restricted to only positive values inside the radical, otherwise you get non-real solutions.

Now let's look at the range of the function, which can be defined as an interval of y-values which can possibly be outputted by the function.

Since as mentioned before, the cube root isn't limited to a certain interval, and rather all real numbers, the range is also similar, since whenever you have a negative number in the radical, the output will be a negative number, so the range is all real numbers

M=-4/5,(-7, - 2) Find the equation of the line that has the given slope
ikadub [295]

Answer: y=-\frac{4}{5}x-\frac{38}{5}

Step-by-step explanation:

To find the equation, you plug in the slope and given point. Then, you can solve and find the y-intercept.

-2=-\frac{4}{5}(-7)+b          [multiply]

-2=\frac{28}{5}+b                  [subtract both sides by \frac{28}{5}]

b=-\frac{38}{5}

Now that we have the y-intercept, the equation is y=-\frac{4}{5}x-\frac{38}{5}.
