Whats the vertex of x^2-12x+23

Step-by-step explanation:

For the first table, to find y, we have to substitute each value of x into the equation.

y = - 3 + 3 = 0 so -3 is going to have the y value as 0

y = -2 + 3 = 1 so -2 is going to have the y value as 1

y = -1 + 3 = 2 so -1 is going to have the y value as 2

y = 0 + 3 = 3 so 0 is going to have the y value as 3

y = 1 + 3 = 4 so 1 is going to have the y value as 4

y = 2 + 3 = 5 so 2 is going to have the y value as 5.

For the next table:

y = 2(-3) + 1 = -5 so -3 is going to have the y value as -5

y = 2(-2) + 1 = -3 so -2 is going to have the y value as -3

y = 2(-1) + 1 = -1 so -1 is going to have the y value as -1

y = 2(0) + 1= 1 so 0 is going to have the y value as 1

y = 2(1) + 1 = 3 so 1 is going to have the y value as 3

y = 2(2) + 1 = 5 so 2 is going to have the y value as 5

For the next table:

y = 2(-3) - 3 = -9 so -3 is going to have the y value as -9

y = 2(-2) - 3 = -7 so -2 is going to have the y value as -7

y = 2(-1) - 3 = -5 so -1 is going to have the y value as -5

y = 2(0) - 3 = -3 so 0 is going to have the y value as -3

y = 2(1) - 3 = -1 so 1 is going to have the y value as -1

y = 2(2) - 3 = 1 so 2 is going to have the y value as 1
