Answer:

x = 1 or

x = - 7

To get rid of the square root. Isolate the square root and it's multiple. Then square both sides to get rid of it. Don't forget to square the multiple, in this case - 2 becomes 4. Solve for x like you normally do.

alekssr [168]
Even though im not giving you the whole answer, let me give you something that will definitely help you:

Review the graph of function f(x).
s344n2d4d5 [400]

The two limits when x tends to zero are:

\lim_{x \to \ 0^-}  f(x) = 1\\\\ \lim_{x \to \ 0^+}  f(x) = 0

<h3 /><h3>How to get the limits when x tends to zero?</h3>

Notice that we have a jump at x = 0.

Then we can take two limits, one going from the negative side (where we will go along the blue line)

And other from the positive side (where we go along the orange line).

We will get:

\lim_{x \to \ 0^-}  f(x) = 1\\\\ \lim_{x \to \ 0^+}  f(x) = 0

Notice that the two limits are different, that means that the function is not a continuous function.
