How do you find the zeros of f(x) = x² - 4?

Back

Factor the equation: (x - 2)(x + 2) = 0, then set each factor to zero: x - 2 = 0 or x + 2 = 0.

Front

What is the vertex form of a quadratic function?

Back

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

Front

What is the significance of the coefficients a, b, and c in the standard form of a quadratic?

Back

a determines the direction and width of the parabola, b affects the position of the vertex, and c is the y-intercept.

How can you determine if a quadratic opens upwards or downwards?

Back

If a > 0, it opens upwards; if a < 0, it opens downwards.
