What is the factorization of $$3x^2 + 11x + 8$$ ?

The factorization is $$ (3x + 8)(x + 1) $$ .

What is the solution to the inequality $$2y - x \le 4$$ ?

Graph the line $$2y = x + 4$$ and shade below it.

What is the equation in standard form of the line that passes through the point (6, -1) and is parallel to the line represented by $$8x + 3y = 15$$ ?

The equation is $$8x + 3y = 45$$ .

How do you find the x-intercept of a linear equation?

Set $$y = 0$$ and solve for $$x$$ .

What is the standard form of a linear equation?

The standard form is $$Ax + By = C$$ where A, B, and C are integers.

What is the difference between a function and a relation?

A function is a relation where each input has exactly one output.

What is the quadratic formula?

The quadratic formula is $$x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}$$ .

What does it mean for two lines to be parallel?

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

What is the vertex of a parabola represented by the equation $$y = ax^2 + bx + c$$ ?

The vertex can be found using the formula $$x = -\frac{b}{2a}$$ .

How do you determine if a relation is a function from a graph?

Use the vertical line test: if a vertical line intersects the graph at more than one point, it is not a function.

What is the range of a function?

The range is the set of all possible output values (y-values) of a function.
