Unit 4a Test Review - Edited

Front

How many solutions (roots) does the graph of a function have if it does not intersect the x-axis?

Back

The graph has no solutions (roots).

Front

What type of function is represented by a straight line?

Back

Linear function.

Front

What type of function has a parabolic shape and can be represented by the equation y = ax² + bx + c?

Back

Quadratic function.

Front

Solve for x: x² = 16

Back

x = ±4.

Front

What does the Zero-Product Property state?

Back

If a product of two factors equals zero, at least one of the factors must be zero.

Front

Solve using the Zero-Product Property: (x + 4)(x − 3) = 0

Back

x = −4 and x = 3.

Front

What is the general form of a linear function?

Back

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

Front

What is the vertex of a quadratic function in the form y = ax² + bx + c?

Back

The vertex can be found using the formula x = -b/(2a).

Front

What is the difference between a linear function and a quadratic function?

Back

A linear function has a constant rate of change, while a quadratic function has a variable rate of change and forms a parabola.

Front

What is the standard form of a quadratic equation?

Back

y = ax² + bx + c.
