Question

Look at photo because I don’t get it

Answer 1

Answer:

a) (-2,2), (-1,-1), (1,-1), (3,7)

b) x=1.4

Answer 2

Answer:

a) (-2, 2), (-1, -1), (1, -1), (3, 7)

b) x = 1.4

Step-by-step explanation:

a) Plug in your x & solve for y.

$y = (-2)^2 - 2\\y = 2\\y = (-1)^2 - 2\\y = -1\\y = (1)^2 - 2\\y = -1\\y = (3)^2 -2\\y = 7$

b) Same thing as a, but just plug in 0 for y & solve for x

$0 = x^2 -2\\2 = x^2\\\sqrt(2) = x\\1.4 = x$
