Please explain for what values of x is function g(x) continuous if it is defined by.
Bond [772]

Using the continuity concept, it is found that the function is continuous for all real values.

<h3>What is the continuity concept?</h3>

A function f(x) is continuous at x = a if it is defined at x = a, and:

\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)

In this problem, we are given a piece-wise function, hence we have to look at the points where the definition of the function changes. In this problem, it can only be discontinuous at x = 0, which we have to verify.

Then:

  • f(0) = 0^2 - 1 = -1.
  • \lim_{x \rightarrow 0^-} = \lim_{x \rightarrow 0} x^2 - 1 = 0^2 - 1 = -1.
  • \lim_{x \rightarrow 0^+} = \lim_{x \rightarrow 0} \frac{1}{x - 1} = \frac{1}{0 - 1} = -1.

The 3 values are equal, hence the function is continuous at x = 0 and for all real values.

What is the length of Line segment M N?<br><br> 58 cm<br> 75 cm<br> 88 cm<br> 116 cm
wlad13 [49]

Answer:

MN=58\ cm

Step-by-step explanation:

we know that

The <u><em>Midpoint Theorem</em></u> states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side

In this problem

M is the mid-point segment AB

N is the mid-point segment BC

so

Applying the Midpoint Theorem

MN is parallel to AC

MN=\frac{1}{2}AC

we have that

AC=116\ cm ---> given problem

substitute

MN=\frac{1}{2}(116)

MN=58\ cm
