Functions and Relations Assessment

Front

What is a function?

Back

A function is a relation that assigns exactly one output (y) for each input (x). It can be represented as a set of ordered pairs, a graph, or an equation.

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) that represent a point in a two-dimensional space, where 'x' is the input and 'y' is the output.

Front

What does it mean for a relation to be a function?

Back

A relation is a function if no two ordered pairs have the same first element (x-value) with different second elements (y-values).

How do you find the value of a function at a specific point?

Back

To find the value of a function at a specific point, substitute the input value into the function's equation and simplify.

Front

What is the zero of a function?

Back

The zero of a function is the value of x for which the function's output (f(x)) is equal to zero.

Front

How do you evaluate an expression with given values?

Back

To evaluate an expression, substitute the given values for the variables and perform the arithmetic operations.

Front

What is the significance of the y-intercept in a linear function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis, indicating the output value when the input is zero.

What is a quadratic function?

How do you determine if a function is linear or quadratic?

Back

A function is linear if its graph is a straight line (degree 1), and quadratic if its graph is a parabola (degree 2).
