What is the vertex of the quadratic function: x^2 + 10x + 24?

• (-5, -1)

• (5, 1)

• (0, 24)

• (-10, 0)

How do you find the range of a quadratic function?

• Determine the vertex and the direction of the parabola (upward or downward). The range will be all values of y that the function can take.

• Calculate the x-intercepts and use them to find the range.

• Use the quadratic formula to find the roots and then determine the range from those values.

• Identify the coefficients of the quadratic equation and apply them to find the range.

What is the vertex of the parabola given by the equation y = x^2 + 4x + 3?

• (-2, 1)

• (1, -2)

• (2, 3)

• (0, 3)

What is the formula to find the y-coordinate of the vertex?

• The y-coordinate is found by substituting the x-coordinate back into the original quadratic equation.

• The y-coordinate is found by taking the derivative of the quadratic equation.

• The y-coordinate is found by using the quadratic formula directly.

• The y-coordinate is found by averaging the x-intercepts.

What is the range of the function y = -2x^2 + 6x + 5?

• y ≤ 6

• y ≥ 6

• y = 6

• y < 6

Find the vertex of the quadratic function: y = 4x^2 + 24x + 5

• (-3, -31)

• (3, 31)

• (0, 5)

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

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

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

• The domain and range are the same and represent all values of the function.

• The domain is the set of all values that the function can never take, while the range is the set of all values that the function can take.

What is the vertex of a quadratic function?

• The point where the parabola changes direction, found using the formula @@x = -\frac{b}{2a}@@.

• The highest point of the parabola, always located at the y-intercept.

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

• The midpoint of the line segment connecting the x-intercepts.
