Algebra 1 EOC Vocabulary

Front

What is the minimum value of a quadratic function?

Back

The minimum value is the lowest point on the graph of the function, occurring at the vertex when the parabola opens upwards.

Front

What is the X-Intercept of a graph?

Back

The X-Intercept is the point where the graph crosses the x-axis, meaning the value of y is zero at that point.

Front

What does f(x) represent in mathematics?

Back

f(x) represents function notation, indicating the output of a function f for a given input x.

Front

What does it mean if a system of equations has no solution?

Back

It means the lines representing the equations are parallel and will never intersect.

Front

What does the graph of y = -3x² + 7x - 2 look like?

Back

The graph opens downwards and has a maximum value at its vertex.

Front

What is a quadratic function?

Back

A quadratic function is a polynomial function of degree 2, typically in the form f(x) = ax² + bx + c.

Front

What is the vertex of a parabola?

Back

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

Front

What is the axis of symmetry in a quadratic function?

Back

The axis of symmetry is a vertical line that divides the parabola into two mirror-image halves, passing through the vertex.

Front

What does it mean for two lines to be coinciding?

Back

Coinciding lines are lines that lie on top of each other, representing the same equation and having infinitely many solutions.

Front

What is the range of a quadratic function that opens upwards?

Back

The range is all real numbers greater than or equal to the minimum value.
