What is the equation of this graph?

• f(x) = (x -5)² + 1
• f(x) = (x - 1)² - 5
• f(x) = (x + 1)² - 5
• f(x) = (x + 5)² +1

How did we transform from f(x) =x²

to

g(x) = -3x²

• reflection in x-axis and vertical shift down

• reflection x-axis and vertical stretch

• horizontal stretch

• reflection x-axis and down 3

Find the zeros by factoring: y= x²+9x+18

• -6 and -3
• 6 and 3
• 9 and 2
• -9 and -2

Solve the system:

 $y=x^2-6x+13$  

 $y=x+3$  

• (2, 5) and (5, 2)

• (2, 5) and (5, 8)

• (5, 8) and (8, 5)

• (8, 5) and (8, 8)
