Front

What are the zeros of a function?

Back

The zeros of a function are the values of x for which the function equals zero. They are the x-intercepts of the graph.

Front

What is the quadratic formula?

Back

The quadratic formula is used to find the solutions (or roots) of a quadratic equation and is given by x = (-b ± √(b² - 4ac)) / (2a).

Front

What does it mean if a root has a multiplicity of 2?

Back

If a root has a multiplicity of 2, it means that the root is repeated twice, and the graph will touch the x-axis at that point and bounce off.

Front

What is the distance formula?

Back

The distance formula calculates the distance between two points (x1, y1) and (x2, y2) in a coordinate plane: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the midpoint formula?

Back

The midpoint formula finds the midpoint between two points (x1, y1) and (x2, y2): M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the slope formula?

Back

The slope formula calculates the slope (m) between two points (x1, y1) and (x2, y2): m = (y2 - y1) / (x2 - x1).

Front

What is the sine function?

Back

The sine function, denoted as sin(x), is a trigonometric function that relates the angle x to the ratio of the opposite side to the hypotenuse in a right triangle.

Front

What is the cosine function?

Back

The cosine function, denoted as cos(x), is a trigonometric function that relates the angle x to the ratio of the adjacent side to the hypotenuse in a right triangle.

Front

What is the exponential function?

Back

The exponential function is a mathematical function of the form f(x) = e^x, where e is Euler's number, approximately equal to 2.71828.

Front

What is a polynomial function?

Back

A polynomial function is a function that can be expressed in the form f(x) = a_n*x^n + a_(n-1)*x^(n-1) + ... + a_1*x + a_0, where a_n are constants and n is a non-negative integer.
