What is the rate of change in a linear function?

Back

The rate of change in a linear function is the slope, which represents how much the dependent variable (y) changes for a unit change in the independent variable (x).

What does a non-linear function indicate about its rate of change?

Back

A non-linear function indicates that the rate of change is not constant; it varies at different points along the curve.

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1).

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x = 0.

Front

What is the definition of equivalent expressions in algebra?

Back

Equivalent expressions are different expressions that have the same value for all values of the variable(s).

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 from a graph?

Back

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

What is an exponential function?

Back

An exponential function is a mathematical function of the form f(x) = a * b^x, where a is a constant, b is the base, and x is the exponent.
