Answer:

The graph stretches horizontally by a factor of 4 and shifted up by 1 unit.

Explanation:

Given:

The function
f(x) is given as:


f(x)=3\sin (x)+1

The function
g(x) is given as:


g(x)=3\sin ((x)/(4))+2

The function 'g' can be rewritten as:


g(x)=3\sin ((x)/(4))+1+1

So, the 'x' value of 'f' is multiplied by
(1)/(4) and 1 unit is added to the function to get the function 'g'.

Therefore, as per transformation rules:

1.
f(x)\to f(Cx)

  • 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.
f(x)\to f(x)+C

  • If C > 0 ⇒ The graph shifts up by 'C' units.
  • If C < 0 ⇒ The graph shifts down by 'C' units.

Therefore, the graph of
f(x) stretches in the x direction(horizontally) by a factor of 4 and shifts up by 1 unit to get
g(x).
