Hey there!

<u>Find </u><u>f(</u><u>-</u><u>3</u><u>)</u><u> </u><u>:</u>

  • Answer :

f(-3) = 8 ✅

  • Explanation :

f(x) = -x + 5

<em>></em><em>></em><em> </em><em>Substitute </em><em>-</em><em>3</em><em> </em><em>for </em><em>x </em><em>in </em><em>f(</em><em>x)</em><em> </em><em>:</em><em> </em>

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

f(-3) = 3 + 5

f(-3) = 8

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

       <em>Given f(x)=-x+5, find f(-3).</em>

<em>     </em>\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)=}

<h3> What we need to do:-</h3>

  • 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}

<h3>Good luck with your studies. \ddot\smile</h3>
