Front

Does y = -4x^2 have a maximum or minimum value?

Back

maximum

Front

What is the formula for the nth term of an arithmetic sequence?

Back

a_n = a_1 + (n-1)d, where a_1 is the first term and d is the common difference.

Front

What is the vertex form of a quadratic function?

Back

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

Front

How do you find the axis of symmetry for a quadratic function?

Back

x = -b/(2a), where ax^2 + bx + c is the standard form.

Front

What is the difference between maximum and minimum values in a quadratic function?

Back

Maximum is the highest point on the graph, minimum is the lowest point.

Front

What does the discriminant tell you about a quadratic equation?

Back

It indicates the nature of the roots: positive (two real roots), zero (one real root), negative (no real roots).
