Question

F(x)=x-5; translation 4 units up

Answer 1

`f(x)=x-1`

Step-by-step explanation

To move a function up, you add outside the function: f (x) + b is f (x) moved up b units

so , we have

`f(x)=x-5`

to traslate the function 4 units up, we have to add (4) units, so

`\begin{gathered} f(x)=x-5\rightarrow traslate(\text{ ad4)}\rightarrow f(x)=x-5+4 \\ f(x)=x-1 \end{gathered}`

therefore, the answer is

`f(x)=x-1`

I hope this helps you
