Front

What is the definition of the y-intercept of a function?

Back

The y-intercept is the point where the graph of a function intersects the y-axis, represented as (0, y).

Front

How do you find the y-intercept from a function's equation?

Back

To find the y-intercept, set x = 0 in the function's equation and solve for y.

Front

What is the definition of the x-intercept of a function?

Back

The x-intercept is the point where the graph of a function intersects the x-axis, represented as (x, 0).

Front

How do you find the x-intercept from a function's equation?

Back

To find the x-intercept, set y = 0 in the function's equation and solve for x.

Front

What is the growth factor (b-value) in an exponential function?

Back

The growth factor (b-value) is the base of the exponential function, indicating how much the function's value increases for each unit increase in x.

Front

In the function f(x)=2(4)^x, what does the '2' represent?

Back

The '2' represents the initial value or the y-intercept of the function when x = 0.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you determine the range of a function from its graph?

Back

To determine the range from a graph, identify the lowest and highest y-values that the graph reaches.

Front

What does the notation y > -6 indicate about the range of a function?

Back

It indicates that the function's output values (y-values) are greater than -6, meaning the function does not reach or go below -6.

Front

What is the significance of intercepts in graphing functions?

Back

Intercepts help identify key points on the graph, making it easier to sketch the function and understand its behavior.
