Answer:
   g(x) = (1/6)(x +7)^2 -8
Step-by-step explanation:
The transformation ...
   g(x) = a·f(x -h) +k 
represents vertical scaling by a factor of 'a', right shift by h units, and up shift by k units. You want the function g(x) for f(x) = x^2, a = 1/6, h = -7, and k = -8. Those transformations give you ...
   g(x) = (1/6)(x +7)^2 -8

Answer:

Step-by-step explanation:
So we have the two functions: 

And we want to find f(g(-2)). 
First, let's find g(-2): 

Multiply: 

Subtract: 

Now, substitute: 

Now, find the value of f(-20): 

Multiply: 

Add: 

So: 

And we're done!

Answer:
y = -x+3
Step-by-step explanation:
We have two points so we can find the slope
m =(y2-y1)/(x2-x1)
     (1-2)/(2-1)
     -1/1
  The slope is -1
We can use the slope intercept form of the equation
y = mx+b where m is the slope and b is the y intercept
y = -x+b
Substitute a point into the equation to find b
2 = -1 +b
Add 1 to each side
2+1 =-1+1 +b
3 =b
y = -x+3
