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

How would shift the parent function y=x^2 to graph the function y=(x-4)^2+5

• The function would be shifted 4 units to the right and 5 units down.

• The function would be shifted 4 units to the right and 5 units up

• The function would be shifted 5 units to the right and 4 units down

• The function would be shifted 5 units to the left and 4 units up.

• Maximum or Minimum

• Vertex

• Midpoints of the x-intercept

• y-intercept

The parent function f\left(x\right)=x^2 is reflected across the x-axis, vertically stretched by a factor of 4 and translated right 3 units to create g(x). Use the description to write the quadratic function in vertex form.
