What does it mean if the graphs of a quadratic and linear equation have no real solutions?

Back

The graphs do not intersect.

Front

What is the vertex form of a quadratic equation?

Back

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

Front

What is the difference between congruent and similar shapes?

Back

Congruent shapes are the same size and shape; similar shapes are the same shape but different sizes.

Front

If a quadratic equation opens downwards, what can be said about its leading coefficient?

Back

The leading coefficient is negative.

Front

What is the maximum height of a projectile described by the equation h = -5(t - 2)^2 + 10?
