Answer:

To make f continuous at x=2, f(2) should be defined x = 2.

Step-by-step explanation:

A function, let say f(x), is defined at x = c is continuous at x = c

If the limit of f(x) as x approaches c is equal to the value of f(x) at  x = c.

Mathematically it is written as:

if

\lim _{x\to c}\:f\left(x\right)=f\left(c\right)

then

f(x) is continuous at  x = c.

So from the above definition, we conclude that:

To make f continuous at x=2, f(2) should be defined x = 2.

i.e.

if

\lim _{x\to 2}\:f\left(x\right)=f\left(2\right)

then

f(x) is continuous at  x = 2.

WHAT ARE THE SIMILARITIES AND DIFFERENCES OF LINEAR AND NON-LINEAR SYSTEMS OF EQUATIONS.
blagie [28]
SIMILARITIES
 Some similarities are that for linear and non-linear systems of equations, you need the same number of equations as unknowns to solve the system and find the only solution for each variable.
 DIFFERENCES
 Some differences are
 The linear system of equations has degree "1" in each of its variables.
 The non-linear system of equations has degree "n" in each of its variables.
  where n = 1,2,3, ..., i, ..., n.

What is the range the 3rd side of the triangle can be be with 15 cm 14 cm ?
Volgvan

Answer:

20.5 cm

Step-by-step explanation:

I just used Pythagorean theorem  in which c^2=a^2+b^2

so this is c^2= 225 + 196 and then you get c^2= 421 and finally you get the square root of 421 so this way you finally get 20.5 cm
