in the places there is X you put -3 , -3 squared minus 7 is equal to 9 , 9-7 is equal to 2

Answer 2

Answer:

$\large{ \tt{❃ \: EXPLANATION}} :$

• 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 ).

$\large{ \tt{❁ \: LET'S \: START}} :$

• When x = ( - 3 ) ,

$\large{ \tt{⋆ \: f( - 3) = {( - 3)}^{2} - 7}}$

$\large{ \tt{↦ \: f( - 3) = ( - 3) \times ( - 3) - 7}}$

• Multiplying a negative integer by a negative integer gives a positive integer!

$\large{ \tt{↦f( - 3) = 9 - 7}}$

$↦ \large{ \tt{f( - 3) = \boxed{ \tt{2}}}}$

• Hence , F ( - 3 ) = 2 .
