To get g(x+2) we start out with this: g(x) = 8x-2 We put parentheses around the x on the right side: g(x) = 8(x)-2 We take out both x's g( ) = 8( )-2 We open the empty parentheses a little wider g( ) = 8( )-2 We put x+2 in the parentheses: g(x+2) = 8(x+2)-2 We leave the left side as it is, but we simplify the right side: g(x+2) = 8x+16-2 g(x+2) = 8x+14 Edwin
