Front

How do you find the y-intercept of a quadratic function?

Back

Set x = 0 and solve for y.

Front

What is the y-intercept of the function y = x^2 - 6x + 5?

Back

(0, 5)

Front

What does the vertex form of a quadratic function look like?

Back

y = a(x - h)^2 + k, where (h, k) is the vertex.

Front

How do you determine if a quadratic function is increasing or decreasing?

Back

Analyze the vertex and the direction of the parabola.
