ALGEBRA: WEEK OF APRIL 28

Front

What is a quadratic function?

Back

A quadratic function is a polynomial function of degree 2, typically in the form y = ax² + bx + c, where a, b, and c are constants.

Front

Identify the standard form of a quadratic function.

Back

The standard form of a quadratic function is y = ax² + bx + c.

Front

What is the vertex of a quadratic function?

Back

The vertex is the highest or lowest point of the parabola represented by the quadratic function.

Front

How do you convert a percentage to a decimal?

Back

To convert a percentage to a decimal, divide the percentage by 100.

Front

What is the factored form of x² - 14x + 45?

Back

(x - 5)(x - 9)

Front

What is the sum of the roots of the quadratic equation ax² + bx + c = 0?

Back

The sum of the roots is given by -b/a.

Front

What is the product of the roots of the quadratic equation ax² + bx + c = 0?

Back

The product of the roots is given by c/a.

Front

What is a linear function?

Back

A linear function is a polynomial function of degree 1, typically in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the difference between linear and quadratic functions?

Back

Linear functions have a constant rate of change and graph as straight lines, while quadratic functions have a variable rate of change and graph as parabolas.

Front

How do you combine like terms in algebra?

Back

Combine like terms by adding or subtracting the coefficients of terms that have the same variable raised to the same power.
