If the original parabola is defined by y=x^2 how would it change y=2\left(x-3\right)^2+1 were graphed instead

• The parabola would be vertically stretched by a factor of 2, tanslated right 3, up 1

• The parabola would be vertically compressed by a factor of 1/2, translated left 3, down 1

• The parabola would be vertically compressed by a factor of 1/2, translated right 3, down 1

• The parabola would be vertically stretched by a factor of 2, translated left 3, up 1
