#4 the answer is 90° because it's a right angle,#3 is A because you have to follow P.E.M.D.A.S
Answer:
The graph stretches horizontally by a factor of 4 and shifted up by 1 unit.
Step-by-step explanation:
Given:
The function
is given as:

The function
is given as:

The function 'g' can be rewritten as:

So, the 'x' value of 'f' is multiplied by
and 1 unit is added to the function to get the function 'g'.
Therefore, as per transformation rules:
1.
- If C > 1 ⇒ The graph compresses in the x direction.
- If 0 < C < 1 ⇒ The graph stretches in the x direction by factor of 1/C.
2. 
- If C > 0 ⇒ The graph shifts up by 'C' units.
- If C < 0 ⇒ The graph shifts down by 'C' units.
Therefore, the graph of
stretches in the x direction(horizontally) by a factor of 4 and shifts up by 1 unit to get
.
Answer:
(9, 6) and (5, 2)
mid point = [ (x1 + x2) / 2 , (y1 + y2) / 2]
=[(9+5)/2 , (6+2)/2]
=[14/2, 8/2]
= (7,4)
Therefore the midpoint is (7,4)
