1) \text{ } f(0)=2(0)^(2)+4(0)-5=\boxed{-5}\\\\2) \text{ } f(2)=2(2)^(2)+4(2)-5=\boxed{11}\\\\3) \text{ } f(-2)=2(-2)^(2)+4(-2)-5=\boxed{-5}\\\\4) \text{ } f(x+1)=2(x+1)^(2)+4(x+1)-5=2(x^(2)+2x+1)+4x+4-5=2x^(2)+4x+2+4x+4-5=\boxed{2x^(2)+8x+1}\\\\5) \text{ } f(-x)=2(-x)^(2)+4(-x)-5=\boxed{2x^(2)-4x-5}
