Transformation involves changing the form of a function

The transformations are:

vertical translation 1 unit up .
horizontal translation 5 units left.

The functions are given as:

[tex]\mathbf{f(x) = 8x}[/tex]

[tex]\mathbf{g(x) = 8(x + 5) + 1}[/tex]

Considering f(x), we have:

[tex]\mathbf{f(x) = 8x}[/tex]

Start by translating the function 5 units left.

The rule of this translation is:

[tex]\mathbf{f'(x) = f(x + 5)}[/tex]

So, we have:

[tex]\mathbf{f'(x) = 8(x + 5)}[/tex]

Next, translate the function 1 unit up

The rule of this translation is:

[tex]\mathbf{f''(x) = f'(x) + 1}[/tex]

So, we have:

[tex]\mathbf{f''(x) = 8(x + 5) + 1}[/tex]

Rewrite as:

[tex]\mathbf{g(x) = 8(x + 5) + 1}[/tex]

Hence, the transformations are: vertical translation 1 unit up and horizontal translation 5 units left
