3. (03.06) Using the completing-the-square method, rewrite f(x) = x2 - 8x + 3 in vertex form. (2 points)
O f(x) = (x -8)2
O f(x) = (x -4)2-13
O f(x) = (x –4)2 + 3
O f(x) = (x -4)2 + 16

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
