I'm stuck on a question I'm helping my brother with. We need to find out if y = -x squared is linear or not.

We have that:
Let's name each side of it with f(x) and g(x):
Then, we have that:
Then, the answer is C
<h2>Answer: C</h2>The two limits when x tends to zero are:
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:
Notice that the two limits are different, that means that the function is not a continuous function.
