Question

Given f(x)=½(8-2x), what is the value of f(-5)? help plez

Answer 1

Answer:

9

Step-by-step explanation:

f(x)=½(8-2x)

Let x = -5

f(-5)=½(8-2* (-5))

     =½(8+10)

     =½(18)

     =9

Answer 2

$\\ \tt\bull\rightarrowtail f(x)=1/2(8-2x)$

$\\ \tt\bull\rightarrowtail f(-5)$

$\\ \tt\bull\rightarrowtail 1/2(8-2(-5))$

$\\ \tt\bull\rightarrowtail 1/2(8+10)$

$\\ \tt\bull\rightarrowtail 1/2(18)$

$\\ \tt\bull\rightarrowtail 9$
