Which equation is the vertex form of a quadratic function?

• f(x) = mx + b

• f(x) = a(x - m)(x - n)

• f(x) = ax² + bx + c

• f(x) = a(x - h)² + k

What is the equation of this graph in vertex form?

• f(x) = (x -5)² + 1

• f(x) = (x - 1)² - 5

• f(x) = (x + 1)² - 5

• f(x) = (x + 5)² +1

Given the equation: y = -(x - 4)² - 3,

does this parabola have a maximum or minimum value? Why?

• Maximum, since it is reflected and opens down

• Minimum, since it is concave up

• Maximum, since it opens up

• Minimum, since it is concave down

If the blue graph is f(x) = x² then the red must be...
