Quadratics Graph Notes

What are the coordinates of the vertex? Is it a maximum or a minimum?

• (2, 3); minimum

• (2, 5); maximum

• (2, 3); maximum

• (2, -3); minimum

• (2, -3); maximum

Find the y-intercept (write as a point)

y = x² - 6x + 5

• (0, 2)

• (0, - 6)

• (5, 0)

• (0, 5)

• (-2, 0)
