Question

The minimum point of a quadratic curve is (7,-4).

Write down the equation of the curve in the form y = (x + a)² + b, where
a and b are numbers.
What are the values of a and b?

Answer 1

the minimum or lowest point for a curve or namely the U-turn, it'd be the same as saying the maximum and equally its U-turn, which is another name for its vertex.
