f-2v

Short Answer

Expert verified

The value of f-2v is -10v-9.

Step by step solution

01

– Putting value of x

We will put -2v in place of xto determine the value of the function.

02

– Simplifying the given function

As, we have:

fx=5x-9

We will put x=-2v:

f鈭�2v=5鈭�2v鈭�9f鈭�2v=鈭�10v鈭�9

03

– Determining the final answer 

f-2v=-10v-9
