Front

What is the parent function of a linear equation?

Back

The parent function of a linear equation is f(x) = x.

Front

What does it mean to expand an expression in algebra?

Back

To expand an expression means to multiply out the factors and simplify the expression.

Front

What is the parent function of a quadratic equation?

Back

The parent function of a quadratic equation is f(x) = x^2.

Front

Define a polynomial function.

Back

A polynomial function is a function that can be expressed in the form f(x) = a_nx^n + a_{n-1}x^{n-1} + ... + a_1x + a_0, where a_n, a_{n-1}, ..., a_0 are constants and n is a non-negative integer.

Front

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the polynomial.

Front

What is the difference between a linear function and a quadratic function?

Back

A linear function has a degree of 1 and its graph is a straight line, while a quadratic function has a degree of 2 and its graph is a parabola.

Front

What is the standard form of a quadratic equation?

Back

The standard form of a quadratic equation is f(x) = ax^2 + bx + c, where a, b, and c are constants.

Front

What is the vertex of a parabola?

Back

The vertex of a parabola is the highest or lowest point on the graph, depending on whether it opens upwards or downwards.
