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

So we can evaluate each separately and then subtract.
f-h4=f4-h(4)
f4=24+3
=8+3=11f4=11
h4=7-43
=33=1 h4=1
This is our final answer.
f-h4=11-1=10
Next we are to compare two pairs of the functions into each other. First we will work out. f°gx=f(gx) This means the rule of f will work on g.
=fx2-3 Here f is now going to work on the rule of g. =2x2-3+5 The rule of f is applied to g.
=2x2-6+5 Simplifying
f°gx=2x2-1 The final results.

Now we will compose the following:
h°gx=h(gx) The rule of h will work on g.
=hx2-3
=-7+(x2-3)3 The rule of h is applied to g. h°gx=-10+x23 The final results.

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 put a -6 in with x to be squared. * Seven units downward means to put -7 outside of the squaring. * The new functions will look like this:

gx=(x-6)2-3-7
gx=(x-6)2-10
Our last job is to find the inverse of two of our functions, f and h. To find the inverse we will write the function with y instead of the function name, then we will switch the places of x and y, and solve for y again. Here are the functions: fx=2x+3 hx=7-x3

Here we replace f(x) and h(x) with y:
y=2x+3 y=7-x3
Here we switch the y and the x:
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...

The following functions will be used in this week’s assignment.
1. fx=2x+5
2. gx=x2-3
3. hx=7-x3
We are first asked to compute f-h4. Like many algebra problems, the solution becomes obvious, or at least easier, once it has been rewritten into a different format. We will solve the problem in this way:
f-h(4) - Original expression
f4-h4 - Rewritten...
