23. Without graphing find the vertex and maximum or minimum value of f (x) f (x) = -4 / 7 (x – 5 )^2 + 1.

What is the vertex?

Is there a maximum or minimum value of f (x)?

What is the maximum value?

24. Write the quadratic function in the form a (x – h)^2 + k. F (x) = x^2 – 8x + 17 25. Find the vertex and line of symmetry then graph the function. Y = 2x^2 – 20x + 52 26. Use the vertex and line of symmetry to graph the function f (x) = x^2 + 2x -2 27. Find the vertex and the axis of symmetry and graph the function. F (x) = x^2 – 9x

The vertex is ------------

What is the axis of symmetry x= -------------

28. Find the vertex, the line of symmetry, the maximum or minimum value of the quadratic function, and graph the function f (x) = 4x^2 – 8x + 7 1. The vertex is ---------------------- 2. The line of symmetry is --------------------------- 3. The maximum / minimum of f (x) is ----------------------- 4. Does f (x) have a maximum or minimum value? 29. Find the x intercepts and y intercepts for f (x). fx = x^2 – 8x + 9 Find the x intercepts for f (x). Select the choice.

The intercept (8) is/are --------------------------

There is no intercept ----------------------------

Find the y intercepts for f(x) select the correct choice.

The y intercept is / are ----------------------

Type an ordered pair. Simplify answer.

There is no y intercept.

30. Find the x and y intercepts f (x) = 4x^2 – x + 12 The y intercept is ------------------------- Simplify answer. Write an ordered pair.

23. Without graphing find the vertex and maximum or minimum value of f (x) f (x) = -4 / 7 (x – 5 )^2 + 1. What is the vertex? Ans: (f(x)-1)= -4 / 7 (x – 5 )^2, (5,1) will be the vertex Is there a maximum or minimum value of f (x)? Ans: f(x) can take maximum value when (x-5)=0 What is the maximum...
