In order to graph f%28x%29=4%5E%28x-3%29, we need to plot some points:


Note: I'll use "y" in place of f(x)


Let's find the y value when x=0


y=4%5E%28x-3%29 Start with the given equation


y=4%5E%280-3%29 Plug in x=0


y=4%5E%28-3%29 Subtract


y=1%2F4%5E%283%29 Flip the fraction to make the exponent positive


y=1%2F64 Cube 4 to get 64


y=0.015625 Divide.


So when x=0, then y=0.015625



-----------------------------------------------


Now let's find the y value when x=1


y=4%5E%28x-3%29 Start with the given equation


y=4%5E%281-3%29 Plug in x=1


y=4%5E%28-2%29 Subtract


y=1%2F4%5E%282%29 Flip the fraction to make the exponent positive


y=1%2F16 Square 4 to get 16


y=0.0625 Divide.


So when x=1, then y=0.0625



-----------------------------------------------



Now let's find the y value when x=2


y=4%5E%28x-3%29 Start with the given equation


y=4%5E%282-3%29 Plug in x=2


y=4%5E%28-1%29 Subtract


y=1%2F4%5E%281%29 Flip the fraction to make the exponent positive


y=1%2F4 Raise 4 to the first power to get 4


y=0.25 Divide.


So when x=2, then y=0.25



-----------------------------------------------



Now let's find the y value when x=3


y=4%5E%28x-3%29 Start with the given equation


y=4%5E%283-3%29 Plug in x=3


y=4%5E%280%29 Subtract


y=1 Raise 4 to the zeroth power to get 1


So when x=3, then y=1



-----------------------------------------------


Now let's find the y value when x=4


y=4%5E%28x-3%29 Start with the given equation


y=4%5E%284-3%29 Plug in x=4


y=4%5E%281%29 Subtract


y=4 Raise 4 to the first power to get 4


So when x=4, then y=4



-----------------------------------------------


Now let's find the y value when x=5


y=4%5E%28x-3%29 Start with the given equation


y=4%5E%285-3%29 Plug in x=5


y=4%5E%282%29 Subtract


y=16 Square 4 to get 16


So when x=5, then y=16



-----------------------------------------------


So we have the following values:


xy
00.015625
10.0625
20.25
31
44
516




Now let's plot these points





Now draw a curve through those points to graph f%28x%29=4%5E%28x-3%29
