Front

Zeros

Back

The zeros of a function f(x) are the values of x where the function is equal to zero.

Front

x-Intercepts

Back

The x-intercepts of a graph are located where the graph crosses the x-axis and where f(x) = 0.

Front

Literal Equation

Back

A formula or equation that consists primarily of variables.

Front

Back

Solutions to the equation are the x-coordinates of the points where the function crosses the x-axis.

Front

Quadratic Equation (number of real solutions)

Back

Cross x-axis twice then 2 solutions, touches x-axis once then 1 solution, doesn't touch the x-axis at all then 0 solutions.
