<em><u>intercepts</u></em>

y = x^2 - 9x + 20

y = (x - 5)(x - 4)

x-ints at (5, 0) and (4, 0)

y = (0 - 5)(0 - 4)

y = 20

y-int at (0, 20)

<em><u>vertex</u></em>

y = 1x^2 - 9x + 20

-b / 2a = 9/2(1)

vertex (4.5, y)

y = (x - 5)(x - 4)

y = (4.5 - 5)(4.5 - 4)

y = -0.5(0.5)

y = -0.25

vertex (4.5, -0.25)

i recommend using desmos if in the future you need help

Answer: Option B) 7,214

Step-by-step explanation:

The value of the digit 2 in 5,426 is 20.

-In 2,843, the place value of 2 is 2000

- In 7,214, the place value of 2 is 200

- In 43,928, the place value of 2 is 20

- In 67,452, the place value of 2 is 2

So, since he place value of 2 in 7,214 is 200; and since 200 is ten times more than 20 (i.e 20 x 10 = 200)

Thus, the answer is 7214
