Answer:
( 4, 11 ) , ( - 4, 27 )
Step-by-step explanation:
f(x) = x² - 2x + 3
f(x) = - 2x + 19
x² - 2x + 3 = - 2x + 19
x² - 16 = 0
( x + 4 )( x - 4 ) = 0
[tex]x_{1}[/tex] = - 4
[tex]x_{2}[/tex] = 4
f(x) = [tex]y_{1}[/tex] = - 2( - 4 ) + 19 = 27
[tex]y_{1}[/tex] = 27
f(x) = [tex]y_{2}[/tex] = - 2( 4 ) + 19 = 11
[tex]y_{2}[/tex] = 11
( 4, 11 ) , ( - 4, 27 )
