Axis of Symmetry Vertex Calculating

What is the axis of symmetry for g(x) = x² - 8x + 7

• x = -1

• x = -3

• x = 4

• x = 7

Find the Vertex:
f(x) = x² + 10x + 21

• (-5,-4)

• (1,10)

• (10,21)

• No Real Solution

What is the axis of symmetry for x² - 14x + 48

• x = -8

• x = -7

• x = -6

• x = 6

• x = 7

What is the vertex of the quadratic function:
y = x² - 6x + 11?

• (3,2)

• (-3,-2)

• (-3,2)

• (3,-2)

Find the Vertex:

f(x) = x² + 11x + 18

• (-5.5,-12.25)

• (1,6)

• (6,2)

• (-7, -3)

• (1,5)

• (1,11)

• (3,17)

• (-1,17)

Does the following quadratic equation have a maximum or minimum value? How can you tell?
y=x²+2x-3

• Minimum value, because the a value is positive

• Maximum value, because the b value is positive

• Maximum value, because the a value is positive

• Minimum value, because the c value is negative

Use the picture to find the vertex and axis of symmetry

• Vertex (3,8) Axis x = 3

• Vertex (3,8) Axis y = 3

• Vertex (8,3) Axis x = 3

• Vertex (8,3) Axis y = 3
