IM Algebra 1 Unit 4 Assessment Review

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output for each input from its domain.

Front

What does the notation f(x) represent?

Back

f(x) represents the output of the function f for the input x.

Front

What is the absolute value function?

Back

The absolute value function, denoted as |x|, returns the non-negative value of x.

Front

How do you find the inverse of a function?

Back

To find the inverse of a function, swap the input and output values and solve for the new output.

Front

What is a piecewise function?

Back

A piecewise function is a function defined by different expressions for different intervals of the domain.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you determine if a function is linear?

Back

A function is linear if it can be represented by a straight line on a graph, typically in the form y = mx + b.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

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

Back

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