Math I: 1st Semester: Final Review (24 - 25)

Front

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

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

Simplify the expression: (2x + 5)(x + 3)

Back

Front

What does it mean for a function to be linear?

Back

A function is linear if it can be represented by a straight line on a graph, typically in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is a linear inequality?

Back

A linear inequality is an inequality that involves a linear function. It can be expressed in the form ax + b < c, ax + b > c, etc.

Front

How do you find the range of a set of values?

Back

To find the range, identify the smallest and largest values in the set. The range is the difference between these two values.

Front

What is the process of simplifying an expression?

Back

Simplifying an expression involves combining like terms, reducing fractions, and performing operations to make the expression as simple as possible.

Front

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

Back

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

Front

What does the symbol '≥' mean in inequalities?

Back

The symbol '≥' means 'greater than or equal to', indicating that the value can be either greater than or equal to a specified number.

Front

What is the difference between '>' and '≥'?

Back

The symbol '>' means 'greater than', while '≥' means 'greater than or equal to'. The latter includes the possibility of equality.
