What is the vertex form of the quadratic function?

• f(x) = ax² + bx + c

• f(x) = a(x-h)² + k

• f(x) = a(x+h)² - k

• f(x) = x²

Convert the quadratic equation y = x^2 - 2x + 5 into vertex form.

Write the following quadratic expression in vertex form

x² + 14x + 50

• (x + 7)² + 1

• (x - 7)² - 1

• (x - 7)² + 1

• (x + 7)² - 1
