Foundations of Math 1 Exam Review

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise over run).

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the solution to the inequality -3 − 6(4x + 6) > -111?

Back

x < 3.

Front

What is a Recursive Formula?

Back

A Recursive Formula defines each term of a sequence using the preceding term(s).

Front

What is an Explicit Formula?

Back

An Explicit Formula allows you to find the nth term of a sequence without needing to know the previous terms.

Front

What is the value of f(-1) for the function f(x) = 2x² + 5x - 17?

Back

f(-1) = -20.

Front

What is the order of operations in mathematics?

Back

The order of operations is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), often abbreviated as PEMDAS.

Front

What is the result of the expression 36 - [1 + (7 x 2)] - (3 + 1)?

Back

The result is 17.

Front

What is a Quadratic Function?

Back

A Quadratic Function is a polynomial function of degree 2, typically in the form f(x) = ax² + bx + c.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as x increases, the value of f(x) also increases.
