Answer 1

Answer:

a) x=-2 then y=10

   x=-1 then y=5

   x=1 then y=1

   x=3 then y= 5

b)x=-0.8;x=2.8

Step-by-step explanation:

a) We have the formula $y=x^{2} -2x+2$

Instead of x, we will plug in the given value to find y.

If x=-2:

$y=(-2)^{2} -2*(-2) +2\\y=4+4+2\\y=10$

If x=-1:

$y=(-1)^{2} -2*(-1)+2\\y=1+2+2\\y=5$

If x=1:

$y=1^{2} -2*1+2\\y=1-2+2\\y=1$

If x=3:

$y=3^{2} -2*3+2\\y=9-6+2\\y=5$

b) We know when x=0 then y=2

We need to move two boxes up to get to y=4

We can estimate that x = -0.75;x=2.75

We are supposed to round it to the 1. decimal place.

x=-0.8;x=2.8

Answer 2

Answer:

a) x=-2 then y=10

  x=-1 then y=5

  x=1 then y=1

  x3 then y= 5
