What are the x-intercepts of a function?

Back

The x-intercepts of a function are the points where the graph of the function crosses the x-axis. At these points, the value of y is 0.

What is the quadratic formula used for solving quadratic equations?

Back

The quadratic formula is x = (-b ± √(b² - 4ac)) / (2a), where a, b, and c are coefficients in the equation ax² + bx + c = 0.

How do you find the average of three values?

Back

To find the average, sum the values and divide by the number of values. For example, the average of t + 4, t, and t - 2 is (3t + 2) / 3.

Front

What are the roots of the function f(x) = (x - 2)(x + 3)?

Back

The roots of the function are x = 2 and x = -3.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

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

Back

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

Front

How do you solve a system of equations using substitution?

Back

To solve a system of equations using substitution, solve one equation for one variable and substitute that expression into the other equation.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input (x-value) has exactly one output (y-value).
