Given f(x) = -x + 5, find f(-3). Answer:

Answer 1

Hey there!

Find f(-3) :

• Answer :

f(-3) = 8 ✅

• Explanation :

f(x) = -x + 5

>> Substitute -3 for x in f(x) :

f(-3) = -(-3) + 5

f(-3) = 3 + 5

f(-3) = 8

Therefore, your answer is f(-3) = 8

Answer 2

          $\rule{50}{1}\large\textsf{\textbf{\underline{Question:-}}}\rule{50}{1}$

       Given f(x)=-x+5, find f(-3).

    $\rule{50}{1}\large\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}$

We have the function

$\longmapsto\sf{f(x)=-x+5}$

We need to find

$\longmapsto\sf{f(-3)=}$

What we need to do:-

• Replace x with -3:-

$\longmapsto\sf{f(x)=-(-3)+5}$

Simplifying,

$\longmapsto\sf{f(x)=3+5}$

(which is the exact same thing as 5-3)

Henceforth, We conclude that the answer is

$\longmapsto\sf{f(-3)=8}$

Good luck with your studies. $\ddot\smile$
