Q1. What is the vertex of the quadratic function:

y = x² - 6x + 11?

• (3,2)

• (-3,-2)

• (-3,2)

• (3,-2)

Q2. Determine the vertex of the parabola:

y = 5x² - 20x + 13

• (5, -7)

• (-2, -7)

• (2, -7)

• (-7, -2)

Q3. 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

• (-3, 32)

• (-6, 5)

• (-3, -4)

Q5. Describe the transformations from f(x)=x² to g(x)=1/4x²+4

• gets narrower, shift up 1/4 units

• gets wider, shifts up 4 units

f(x) = x² - 8x + 15.

• x = -4

• x = 4

• y = 4
