What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

Identify the error in the following equation solving process: 1/5x + 6 = 3/5x + 5. The student wrote: 1x + 6 = 3x + 5.

Back

The student did not multiply all terms by the common denominator.

Front

What does the inequality y ≤ 2/5x + 1 represent graphically?

Back

It represents the area below or on the line y = 2/5x + 1.

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

What is the formula for finding the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope m is given by m = \frac{y2 - y1}{x2 - x1}.

Front

What is the difference between the domain and range of a function?

Back

The domain is the set of input values (x-values), while the range is the set of output values (y-values).

How do you determine if a point (x, y) is a solution to an equation?

Back

Substitute the x-value into the equation and see if the resulting y-value matches the y-value of the point.

Front

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, representing the value of y when x = 0.
