Semester exam review day 2

Front

What type of function does a table with a parabolic shape represent?

Back

Quadratic function.

Front

What is the y-intercept of a linear function?

Back

The value of y when x = 0.

Front

Which of the following is NOT a definition of a y-intercept?

Back

The value of x when y = 0.

Front

What finite difference is constant for a quadratic equation?

Back

Second finite difference.

Front

How can you determine if a quadratic function has a maximum or minimum value?

Back

By analyzing the direction of the parabola (upward for min, downward for max).

Front

What is the general form of a quadratic function?

Back

f(x) = ax^2 + bx + c, where a ≠ 0.

Front

What does the vertex of a parabola represent?

Back

The highest or lowest point of the graph.

Front

How do you find the y-intercept of a function from its equation?

Back

Set x = 0 and solve for y.

Front

What is the significance of the coefficient 'a' in a quadratic function?

Back

It determines the direction of the parabola (upward if a > 0, downward if a < 0).

Front

What is the difference between linear and quadratic functions?

Back

Linear functions have a constant rate of change; quadratic functions have a variable rate of change.
