Jasmine used factoring and completing the square to analyze this quadratic function, as shown. f(x) = 22 + 8x + 12
= (x+6)(x + 2)
f(x) = x2 + 8z + 12
= 22 + 8x + 16 - 4
= (x +4)² - 4
What are the zeros, the vertex, and the line of symmetry of the graph of f(x)?

25 ! the line of best fit is h = 5a + 86. predict the height at age 16.
