Alg. 1 Review Unit 1-4

Front

What is a function in mathematics?

Back

A function is a relation that assigns exactly one output value for each input value.

Front

How can you determine if a set of values represents a function?

Back

A set of values represents a function if no two ordered pairs have the same first element.

Front

What is the solution to a system of equations?

Back

The solution to a system of equations is the point where the graphs of the equations intersect.

Front

What does it mean for a graph to shift right and up?

Back

A right shift means the graph moves horizontally to the right, and an up shift means it moves vertically upwards.

Front

How do you find the y-intercept of a linear equation?

Back

To find the y-intercept, set x to 0 and solve for y.

Front

What is the y-intercept of the equation 3x + y = 5?

Back

The y-intercept is 5, which means the point (0, 5) is on the graph.

Front

What is a relation in mathematics?

Back

A relation is a set of ordered pairs, which can represent a function or not.

Front

How can you represent a relation using a table?

Back

A relation can be represented in a table by listing the input values in one column and the corresponding output values in another.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input is associated with exactly one output.

Front

What does it mean for a table to represent a specific relation?

Back

A table represents a specific relation if the pairs in the table match the pairs in the relation.
