What is the RANGE of the function if the domain is given as $$-7 ≤ x ≤ 6$$ ?

The RANGE is $$-8 ≤ y ≤ 2$$ .

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

The slope $$m$$ is calculated as $$m = (y2 - y1) / (x2 - x1)$$ .

What is the definition of a quadratic equation?

A quadratic equation is an equation of the form $$ax^2 + bx + c = 0$$ , where $$a$$ , $$b$$ , and $$c$$ are constants and $$a ≠ 0$$ .

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

The vertex can be found using the formula $$x = -b/(2a)$$ .

What does it mean for a function to be increasing?

A function is increasing if, as the input (x) increases, the output (y) also increases.

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

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

What is the process of completing the square in a quadratic equation?

Completing the square involves rewriting the quadratic in the form $$(x - p)^2 = q$$ to make it easier to solve.
