SHIFTS OF THE PARENT FUNCTION:
+f%28x%29=a%2Ab%5Ex
​​
For any constants a, c and d, the function
+f+%28x+%29=+a%2Ab+%5E%28x%2Bc%29%2Bd
-is stretched vertically by a factor of a if abs%28a%29%3E1
-is compressed vertically by a factor of a if abs%28a%29%3C1
-has a y-intercept of (0,a)
​​ -shifts the parent function vertically d units, in the same direction of the sign of d+
-horizontally c units, in the opposite direction of the sign of c
-the y-intercept becomes (0,+b+%5E+%28c+%2Bd%29)
-the horizontal asymptote becomes y+=+d
-the range becomes (d,infinity).
-the domain, (-infinity ,infinity), remains unchanged

in your case we have f%28x%29+=+-%281%2F2%29+%281%2F6%29%5E%28+x-7%29+%2B9

the equation of the new function, g%28x%29:
- is shifted left 7+units, so we have
g%28x%29+=+-%281%2F2%29+%281%2F6%29%5E%28+x-7%2B7%29+%2B9
g%28x%29+=+-%281%2F2%29+%281%2F6%29%5Ex+%2B9

-stretched vertically by a factor of+6, so we have
g%28x%29+=+6%28-1%2F2%29+%281%2F6%29%5Ex+%2B9
g%28x%29+=+-3%2A%281%2F6%29%5Ex+%2B9

-reflected about the x-axis, so we have
g%28x%29+=%28-1%29%2A%28+-3%29%2A%281%2F6%29%5Ex+%2B9
g%28x%29+=+3%2A%281%2F6%29%5Ex+%2B9

and then shifted downward 9 units, so we have
g%28x%29+=+3%2A%281%2F6%29%5E+x+%2B9-9
g%28x%29+=+3%2A%281%2F6%29%5Ex+


State the y-intercept of g%28x%29.
(x, y) =(0,3)

the domain and range of g%28x%29:
the range becomes (0,infinity)
the domain, (-infinity+,infinity)
