Front

How do you determine if a relation is a function?

Back

A relation is a function if each input (x-value) is paired with exactly one output (y-value).

Front

What is the standard form of a quadratic function?

Front

What does it mean for a function to be translated up 5 units?

Back

It means that every point on the graph of the function is moved vertically upwards by 5 units.

Front

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

Back

The coefficient 'a' determines the direction of the parabola (upward if a > 0, downward if a < 0) and its width (larger |a| makes it narrower, smaller |a| makes it wider).

Front

What is the significance of the x-intercepts of a quadratic function?

Back

The x-intercepts (or roots) of a quadratic function are the points where the graph intersects the x-axis, indicating the values of x for which f(x) = 0.

Front

How do you find the number of bananas left after 7 hours if b(x) = 150 - 6x?

Back

Substituting x = 7 into the function gives b(7) = 150 - 6(7) = 150 - 42 = 108.
