How do you find the range of a quadratic function?

• By finding the roots of the equation

• By determining the vertex and the direction of the parabola

• By calculating the discriminant

• By evaluating the function at several points

How can you determine the equation of a line that is perpendicular to another line?

• Take the same slope as the original line.

• Take the negative reciprocal of the slope of the original line.

• Add 1 to the slope of the original line.

• Subtract the slope of the original line from 0.

What is the range of the function @@f(x) = -3(x-4)@@?

• (-∞, ∞)

• [0, ∞)

• (-3, 3)

• (-∞, 0)

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

• It represents the slope of the function.

• It indicates the output value when the input is zero.

• It shows the maximum value of the function.

• It is the point where the graph crosses the x-axis.

• -2

• 0

• 1/2

• 2

What is the formula for the slope of a line given two points (x1, y1) and (x2, y2)?

• @@m = rac{y2 - y1}{x2 - x1}@@

• @@m = rac{y1 - y2}{x2 - x1}@@

• @@m = rac{y2 + y1}{x2 + x1}@@

• @@m = rac{y1 + y2}{x1 - x2}@@

What does it mean for two lines to be parallel?

• They intersect at a right angle.

• They have different slopes and will meet at some point.

• They have the same slope and will never intersect.

• They are always horizontal lines.

What is the general form of a linear equation?

• y = mx + b

• y = ax^2 + bx + c

• y = m + b

• y = mx^2 + b

What is the vertex of a parabola?

• The point where the parabola intersects the x-axis.

• The highest or lowest point on the graph, depending on whether it opens upwards or downwards.

• The point where the parabola intersects the y-axis.

• The midpoint between the focus and the directrix.
