Write the equation of the quadratic function that is moved to the left three, up four and stretched my a scale factor of 3 Plz help me I have a time quiz

The equation of the quadratic function after the given transformation is

y = 2(x + 3)² + 4 ⇒ D

Step-by-step explanation:

Let us revise some transformation rules

∵ The quadratic equation is y = x²

∵ It is moved to the left three units

→ That means add x by 3 ⇒ 1st rule

∴ y = (x + 3)²

∵ It is moved up 4 units

→ That means add the function by 4 ⇒ 2nd rule

∴ y = (x + 3)² + 4

∵ It is stretched by a scale factor of 2

→ That means multiply the function by 2

∴ y = 2(x + 3)² + 4

The equation of the quadratic function after the given transformation is y = 2(x + 3)² + 4
