Complete the table below for the equation y = x^2 + 2x - 1. Then, graph the equation on the provided graph grid.

y = x^2 + 2x - 1

x = -4

y = -4^2 + 2(-4) - 1

y = 16 + (-8) - 1

y = 7

x = -3

y = -3^2 + 2(-3) - 1

y= 9 + (-6) - 1

y = 2

x = -2

y = -2^2 + 2(-2) - 1

y = 4 + (-4) - 1

y = -1

x = -1

y = -1^2 + 2(-1) - 1

y = 1 + (-2) - 1

y = -2

x = 0

y = 0^2 + 2(0) - 1

y = 0 + 0 - 1

y = -1

x = 1

y = 1^2 + 2(1) -1

y = 1 + 2 -1

y = 2

x = 2

y = 2^2 + 2(2) - 1

y = 4 + 4 - 1

y = 7

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
