Answer:
2 Step-by-step explanation:
in the places there is X you put -3 , -3 squared minus 7 is equal to 9 , 9-7 is equal to 2
Answer:
[tex] \large{ \tt{❃ \: EXPLANATION}} : [/tex]
- We're provided : F ( x ) = x² - 7 & we're asked to evaluate F ( - 3 ).
- All you need to do is to assume the value of x as ( - 3 ).
[tex] \large{ \tt{❁ \: LET'S \: START}} : [/tex]
- When x = ( - 3 ) ,
[tex] \large{ \tt{⋆ \: f( - 3) = {( - 3)}^{2} - 7}}[/tex]
[tex] \large{ \tt{↦ \: f( - 3) = ( - 3) \times ( - 3) - 7}}[/tex]
- Multiplying a negative integer by a negative integer gives a positive integer!
[tex] \large{ \tt{↦f( - 3) = 9 - 7}}[/tex]
[tex]↦ \large{ \tt{f( - 3) = \boxed{ \tt{2}}}}[/tex]
- Hence , F ( - 3 ) = 2 .
