Sketch the graph of
y = ( x -1)2 - 4 .
Solution
Now, it is a parabola .Though, we haven't gotten that far yet and thus we will have to select some values of x, plug them in and calculate the y values.
As indicated earlier, it helps to have an idea of what this graph is liable to look as while picking values of x. Thus, don't worry at this instance why we select the values which we did. After the next chapter you would also be capable to select these values of x.
Following is a table of values for this equation.
x
y
( x, y )
-2
5
( -2, 5)
-1
0
( -1, 0)
-3
(0, -3)
1
-4
(1, -4)
2
( 2, -3)
3
(3, 0)
4
( 4, 5)
Let's check the first one .For the first one we only plug x' -2 into the equation and compute y.
y = ( -2 -1)2 - 4
= ( -3)2 - 4
=9 - 4
= 5
Given is the graph of this equation.
Notice that while we set up the axis system in this instance, we only set up as much as we required. For instance, since we didn't go past -2 along our computations we didn't go much past that along our axis system.
Also, notice that we utilized a different scale on each of the axes. Along the horizontal axis we incremented by 1's whereas on the vertical axis we incremented through 2. It will frequently be done in order to make the sketching easier.
Q. How many permutations can you make of the word STATISTICS? Solution: There are 10 letters in the word STATISTICS, i.e. n=10. Three of them are S's, so n 1 =3, three are T'
If A & B are (-2,-2) and (2,-4) respectively, find the co ordinates of P such that AP =3/7 AB and P lies on the line segment AB.
After seeing some children interacting naturally, write down those features of such interactions that make peer learning potentially a better way of learning. Another point that
time=2.82/4000
Multiplication of complex numbers After that, let's take a look at multiplication. Again, along with one small difference, it's possibly easiest to just think of the complex n
what is the product of the solutions to the equation: x2+4x=-4
Sales increased through only 1/2% last month. If the sales from the previous month were $152,850, what were last month's sales? Multiply through the decimal equivalent of 1/2 %
