Answer 1

Given:

There are given that the function:

`f(x)=4^x`

Step-by-step explanation:

To find any transformation, we need to use the parent function which is given.

Then,

(A): Shifted 4 units up:

`\begin{gathered} f(x)=4^x \\ f(x)=4^x+4 \end{gathered}`

Hence, the new function is shown below:

`f(x)=4^x+4`

(B): Shifted 3 units down.

Then,

`\begin{gathered} f(x)=4^x \\ f(x)=4^x-3 \end{gathered}`

Hence, the new function is shown below:

`f(x)=4^x-3`

(C): Shifted 2 units left:

Then,

`\begin{gathered} f(x)=4^x \\ f(x)=4^(x+2) \end{gathered}`

Hence, the new function is shown below:

`f(x)=4^(x+2)`

(D): Shifted 5 units right.

`\begin{gathered} f(x)=4^x \\ f(x)=4^x-5 \end{gathered}`

Hence, the new function is shown below:

`f(x)=4^x-5`

(E); Reflected about x-axis:

`\begin{gathered} f(x)=4^x \\ f(x)=-4^x \end{gathered}`

Hence, the new function is shown below:

`f(x)=-4^x`

(F): Reflected about the y-axis:

Then,

`\begin{gathered} f(x)=4^x \\ f(x)=4^((-x))_{} \end{gathered}`

Hence, the new function is shown below:

`f(x)=4^((-x))_{}`
