Answer: Option D
g(x) is shifted 3 units to the left and reflected over the x-axis.
Step-by-step explanation:
If we have a main function 
And we perform the transformation:

Then it is fulfilled that:
If
the graph of f(x) moves horizontally h units to the left
If
the graph of f(x) moves horizontally h units to the right
If we have a main function 
And we perform the transformation:

Then it is fulfilled that:
The graph of g(x) is equal to the graph of f(x) reflected on the x axis
In this case we have to:
and 
Therefore
and 
This mean that: g(x) is shifted 3 units to the left and reflected over the x-axis.

Answer:
k=3
Step-by-step explanation:
The given system of equations are


We need to find the value of k if the given system of equation have infinite number of solutions.
If two equations
and
have infinite number of solutions, then

Using this we get




Therefore, the value of k is 3.
Answer:
f(x, y) = Sin(x*y)
We want the second order taylor expansion around x = 0, y = 0.
This will be:

So let's find all the terms:
Remember that:


f(0,0) = sin(0*0) = 1.





Then we have that the taylor expansion of second order around x = 0 and y = 0 is:
sin(x,y) = x*y + x*y + x*y = 3*x*y
