What is the equation of the quadratic function that has vertex (-3, 1) and passes through the point (-2, 4)?
Marat540 [252]
  • Vertex form: y=a(x-h)^2+k , with (h,k) as the vertex.

For this, we will be using vertex form. Firstly, plug the vertex into the vertex form equation:

y=a(x-(-3))^2+1\\y=a(x+3)^2+1

Next, we need to solve for a. Plug in (-2,4) into the x and y coordinates to solve for a as such:

4=a(-2+3)^2+1\\4=a(1)^2+1\\4=a+1\\3=a

Putting our equation together,<u> it's y=3(x+3)^2+1</u>

<u>*Additional section*</u>

  • Standard form: y=ax^2+bx+c

Converting to standard form as such:

y=3(x+3)^2+1\\y=3(x^2+6x+9)+1\\y=3x^2+18x+27+1\\y=3x^2+18x+28
