Question

Graph the function.
y=3(2)^x+1 -4

Answer 1

\[y=3(2)^{x+1}-4\]

Answer 2

first, the first of 1 unit to the left,
you added 1 to the x "inside the parenthesis" so to speak, or in this case, into the exponent..
you shifted the function down by 4 units, because you subtracted 4 units from the overall
3(2)^(x+1)

and finally stretched the function vertically by a scale factor of 3.
