Question

If g(x) = -3x, which option below give the formula for h? - h( x) = 3 x - h( x) = -2 x - h( x) = 2 x - h( x) = -3 x

Answer 1

We have been given:


and,

We need to find,
First of we will calculate and for that we need to plug in into , we get:

Now that we have , we can calculate , we need to plug in the value of into to find .
We get:

Therefore,
Now, we need to find (fogoh)(4), plugging the value of x=4 in our final function, we get:

So, (fogoh)(4)=28.
