g(x)=x^2+4x+2
g(2) = 2^2 +4(2) +2 = 4+8+2 = 14
g(x+2) = (x+2)^2 +4(x+2) + 2
g(x+2) = x^2+4x+4 +4x +8 +2
g(x+2) = x^2 + 8x + 14

g(x) = x^2 + 4x + 2
plug in x = 2 to get g(2) and x = x+2 to get g(x+2)
g(2) = 2^2 + 4(2) + 2 = 4 + 8 + 2 = 14
g(x+2) = (x+2)^2 + 4(x+2) + 2
=>x^2 + 4x + 4 + 4x + 8 + 2
=>x^2 + 8x + 14

subsitute 2 for x
g(2) = 4 + 8 + 2 = 14
and g(x+2) = (x+2)^2 + 4(x+2) + 2
= x^2 + 4x + 4 + 4x + 8 + 2
=x^2 + 8x + 14

g(x)=x^2 + 4x + 2 Substitute the value for x and solve for g(x)
For g(2)
g(x) = x^2 + 4x + 2
g(2) = (2)^2 + 4(2) + 2
g(2) = 4 + 8 + 2
g(2) = 14
For g(x+2)
g(x+2) = (x + 2)^2 + 4(x + 2) + 2
g(x+2) = (x^2 + 4x + 4) + (4x + 8) + 2
g(x+2) = x^2 + 8x+ 14

g(2)= (2)^2+(2*4)+2 = 14
g(x+2) = (x+2)^2 +4(x+2) +2
=x^2 +8x+14
