Given ~
[tex] \: [/tex]
[tex]\tt \: g(x) = - 5x - 5[/tex]
[tex] \: [/tex]
Now , put the value of x.
x = 1
[tex] \tt \: g(1) = - 5(1) - 5[/tex]
[tex] \: [/tex]
[tex]\tt \: g(1) = - 5-5[/tex]
[tex] \: [/tex]
[tex] \underline{\boxed{ \red{\tt \: g(1) = - 10}}}{\green✓}[/tex]
[tex] \: [/tex]
hope helps ~
