Domain of definition of a function is the set of numbers which the variable attains and for which the function is defined.

f(x) = sqrt (5x-10)

here x can have value equal to any real number >=2 because if x attains value less that 2, 5x-10 becomes negative and sqrt(5x-10) has no real value.

therefore the domain of the function f(x) is (2, infinity) inclusive of 2.

liq [111]

I want to say -1. if you first combine like terms the equation would look like 2-2x. then next step i did was divide both sides by negative 2 to get the x by itself. after i did that i got -1 x.

Draw two segments. How many common points is it possible for the segments to have? Explore all possibilities.

Arte-miy333 [17]

A segment is bounded by two endpoints.

The two segments can have up to two common points

Assume the line segments are AB and CD where the length of AB is greater than the length of CD.

The possibilities are:

A point of segment CD lies on segment AB
Both points of segment CD lie on segment AB.

See attachment for both possibilities.

Hence, it is possible for the two segments to have two common points.
