This are used to determine the maximum or minimum of a function. The vertex form of the function is given as y = 3(x+2)² - 5
Vertex form of a function
This are used to determine the maximum or minimum of a function. Give the quadratic equation expressed as:
y = 3x² + 12x + 7
The vertex form of the function will be in the form y = a(x-h)² + k
Complete the square
y = 3(x² + 4x) + 7
y = 3(x² + 4x + 2² - 2²) + 7
y = 3(x+2)² - 3(4) + 7
y = 3(x+2)² - 5
Hence the vertex form of the function is given as y = 3(x+2)² - 5
