Given ~

[tex] \tt \: f(x) = 2x² – 3x – 1[/tex]

[tex] \: [/tex]

put the value of x=8 in given function ~

[tex] \tt \: f(8) = 2 ({8})^{2} - 3(8) - 1[/tex]

[tex] \: [/tex]

[tex] \tt \: f(8) = 2 (64) - 3(8) - 1[/tex]

[tex] \: [/tex]

[tex] \tt \: f(8) = 128 - 24 - 1[/tex]

[tex] \: [/tex]

[tex] \tt \: f(8) = 104 - 1[/tex]

[tex] \: [/tex]

[tex] \underline { \boxed{ \tt \red{f(8) = 103}}}{ \green ✓}[/tex]

[tex] \: [/tex]

hope helps ~
