It means that the graph is discontinuous. It consists of a line that looks like the x axis, but at every integer value of x there will be a hole. The piecewise function will probably contain f(x)=1 or some other function for x equal to an integer. This other function will also be discontinuous because it will consist of isolated points separated by gaps.
Answer:
-149
Step-by-step explanation:
=-11 + (n - 1)(-3)
by observation
when n = 0, 
= 1st term
when n = 1, 
= 2nd term
.....
when n = x, 
= (x+1)th term
hence if we want to find the 48th term, n = 48 - 1 = 47
when n = 47, 
= 48th term
= -11 + (47-1)(-3)
= -11 + 46(-3)
= - 11 - 138
= -149
Answer:
3
Step-by-step explanation:
25% of 12= 3
75% + 25%= 15
Step-by-step explanation:
there is no mathematical problem to solve.
just follow the instructions as given.
this is an exercise for you to get a feeling about what is what. it is imperative that you do it.
there is really nothing to solve.
remember, that a positive slope means the line goes up (from left to right), and a negative slope means the line goes down (again from left to right).
and I am sure you know what vertical and horizontal means.
