I’m not extremely good at math but I think you need to make -x-y=1 into y=mx+b form and then solve your new equation!
Answer:
Step-by-step explanation:
G(f(2+x))=g(2+x)^2+3(2+x)=2(2+x)^2+3(2+x)-2=2(4+4x+x^2)+6+3x=8+8x+2x^2+6+3x=2x^2+11x+14
Ask google because I’m so dumb I can’t even read this ! Have a great day I hope you find your answer
-3x - 3.2 no
-1.2-8 no
-1.2x-3.2 yes
-1.2x+3.2 no
