This hebdomad we have been assigned three maps which we must measure. These are the maps which we have to measure this hebdomad. fx=2x+3 gx=x2-3 hx=7-x3 We have been asked to calculate ( f-h ) ( 4 ) .

So we can measure each individually and so subtract.
f-h4=f4-h ( 4 )
=33=1 h4=1
This is our concluding reply.
Next we are to compare two braces of the maps into each other. First we will work out. f°gx=f ( gx ) This means the regulation of degree Fahrenheit will work on g.
=fx2-3 Here f is now traveling to work on the regulation of g. =2?2-3+5 The regulation of degree Fahrenheit is applied to g.
=2?2-6+5 Simplifying
f°gx=2?2-1 The concluding consequences.

Now we will compose the followers:
h°gx=h ( gx ) The regulation of H will work on g.
=-7+ ( x2-3 ) 3 The regulation of H is applied to g. h°gx=-10+x23 The concluding consequences.

Next we are asked to transform g ( x ) so that the graph is placed 6 units to the right and 7 units downward for where it would be right now. * Six units to the right means to set a -6 in with ten to be squared. * Seven units downward means to set -7 outside of the squaring. * The new maps will look like this:

gx= ( x-6 ) 2-3-7
gx= ( x-6 ) 2-10
Our last occupation is to happen the opposite of two of our maps. degree Fahrenheit and h. To happen the opposite we will compose the map with y alternatively of the map name. so we will exchange the topographic points of ten and y. and work out for Y once more. Here are the maps: fx=2x+3 hx=7-x3

Here we replace f ( ten ) and H ( x ) with Y:
y=2x+3 y=7-x3
Here we switch the Y and the ten:
x=2y+3 x=7-y3
Now we solve for Y:
Subtract 3 from both sides. Multiply both sides by 3. -3+x=2y 3x=7-y
One more solving measure:
Divide both sides by 2. Subtract both sides by 3. -3+x2=y 3x=7-y
y=-3+x2 -y=3x-7
Multiply both sides by -1. y=7-3x
Showing the reverse maps:
f-1x=x+35 h-1x=7-3x
Therefore we have evaluated. combined. composed. and found opposites of our maps.
I have found this week’s assignment to be highly disputing. I hope that the ratings that I have performed are right.
