f(x)=4-5x

Short Answer

Expert verified

The domain of the function f(x)is x|x鈮�45

The value atx=-1is3.

Step by step solution

01

Step 1. Find the domain of the function.

f(x)=4-5x

For domain,

4-5x鈮�04鈮�5xx鈮�45

02

Step 2. Find value of f(x) at x=-1

f(x)=4-5xf(-1)=4-5(-1)f(-1)=4+5f(-1)=9f(-1)=3
