Answer:
k=17
Step-by-step explanation:
Given F(x)=2x+3 shifts 10 units when it is replaced with the graph f(x)=2x-k.
The method to solve this kind of questions is find where the graph meets the x axis then add ten units to it .The obtained x coordinate is the point where the second graph meets the x axis.
Now first find where the F(x)=2x+3 meets the x axis by substituting F(x)=0.


Now add 10 to this x coordinate , we get x1=
=
this is x coordinate where the second line meets the x-axis.
The second line is F(x)=2x-k.
now f(x)=0 and x=17/2
On substitution we get 
k=17
Answer:
(-5,-7)
Step-by-step explanation:
Answer: Second option.
Step-by-step explanation:
Given the function f(x), which is:

And given the function g(x), which is:

You need to substiute the function
into the function
in order to find
.
Therefore, through this procedure, you get this answer:


You can observe that this matches with the second option.
