Answer:

  f(x) = sin(0.62832(x +1))

Step-by-step explanation:

The period of the function is the difference between x=4 and x=-6, which is 10 units. Then the horizontal scaling needs to be such that when x changes by 10, the argument of the sine function changes by 2π. That scaling will make it ...

  f(x) = sin(2π(x/10)) = sin(πx/5)

The upward zero-crossing is seen to be at -1, so this function has been shifted left 1 unit. This requires we replace x with x+1:

  f(x) = sin(π/5(x +1))

If we use the given numerical value for pi, this becomes ...

  f(x) = sin(0.62832(x +1))
