Answer =-31

Explanation:

Greetings !

Firstly, write down the given expression


g(x) = 2x + 8x - 1

simplify it to be more accurate where 2+8=10


g(x) = 10x - 1

plug in -3 in the value of x and simplify the expression


g( -3 ) = 10( - 3) - 1 \\ g( - 3) = - 30 - 1

Thus, subtract the numbers


g( - 3) = - 31

Hope it helps!
