Front

How do you identify a function from a set of points?

Back

A relation is a function if each input (x-value) corresponds to exactly one output (y-value). If any x-value repeats with different y-values, it is not a function.

What is the significance of the base 'b' in an exponential function?

Back

The base 'b' in an exponential function determines the rate of growth or decay. If b > 1, the function grows exponentially; if 0 < b < 1, it decays exponentially.

Front

How do you determine if a graph represents a function?

Back

You can use the vertical line test: if a vertical line intersects the graph at more than one point, the graph does not represent a function.

What is the standard form of a quadratic equation?

Front

What is the difference between linear and quadratic functions?

Back

Linear functions have a constant rate of change and are represented by a straight line, while quadratic functions have a variable rate of change and are represented by a parabola.

Front

What is a common method for factoring quadratic expressions?

Back

A common method for factoring quadratic expressions is to look for two numbers that multiply to 'c' (the constant term) and add to 'b' (the coefficient of the linear term).
