Which of the following is the graph of the quadratic function y = x2 - 4x +4?

B. Graph D

Step-by-step explanation:

Start with the vertex formula for each, y = a(x - h)² + k, where (h, k) → (2, 0) is the vertex, plus, -h gives you the OPPOSITE terms of what they really are, and k gives you the EXACT terms of what they really are. So, insert the vertex into the Vertex Equation FIRST, y = (x - 2)². We reason why there is no k is because it is represented by 0. So, squaring this monomial will give us x² - 4x + 4. Ta Da!

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
