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

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

yes
