Unit 3 (Part 1) Review (Final)

Front

What effect does adding a constant to a function have on its graph?

Back

Adding a constant to a function moves the graph vertically. If the constant is positive, the graph moves up; if negative, it moves down.

Front

What is the general form of a quadratic function?

Back

Front

How do you determine if a polynomial function is positive or negative based on its graph?

Back

A polynomial function is positive if the graph is above the x-axis and negative if it is below the x-axis.

Front

What is the inverse of a function?

Back

Front

How do you find the end behavior of a polynomial function?

Back

The end behavior of a polynomial function is determined by the leading term. If the leading coefficient is positive and the degree is even, it approaches positive infinity on both ends.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex of a quadratic function is the highest or lowest point on the graph, depending on the direction of the parabola.

Front

What does it mean for a function to be increasing or decreasing?

Back

A function is increasing if its graph rises as you move from left to right, and decreasing if it falls.

Front

What is the formula for finding the inverse of a linear function?

Back

Front

What is the effect of a negative leading coefficient in a polynomial function?

Back

A negative leading coefficient means the graph will fall to negative infinity as x approaches positive infinity.

How do you identify the x-intercepts of a quadratic function?
