Understanding Linear, Exponential, and Quadratic Functions

What shape does a quadratic function form on a graph?

• A sliding curve

• A circle

• A parabola

• A straight line

Which type of function is represented by a sliding curve on a graph?

• Quadratic

• Exponential

• Linear

• Cubic

Which of the following is a characteristic of an exponential function's equation?

• The equation has no exponents

• The highest exponent is 2

• The variable is in the exponent

• The equation is a constant

What is a key feature of a linear equation?

• It includes a variable in the exponent

• It has no exponents with the variable

• It has a highest exponent of 2

• It is always a constant

What is a characteristic of a quadratic equation?

• The equation is a constant

• The highest exponent is 2

• The variable is in the exponent

• The equation has no exponents

Which function type is not linear, quadratic, or exponential?

• Quadratic

• Cubic

• Exponential

• Linear

What should you look for in a word problem to identify an exponential relationship?

• A parabola

• A straight line

• Growth and decay

• A constant rate of change

In a word problem, what does a constant rate of change suggest?

• A quadratic relationship

• An exponential relationship

• A cubic relationship

• A linear relationship

How can you identify a linear relationship from a table of values?

• The rate of change is constant

• The second difference is constant

• The values form a parabola

• The values are all positive

What does a constant second difference in a table of values indicate?

• An exponential function

• A linear function

• A cubic function

• A quadratic function
