Domain, x={ -2, -1, 0, 1, 2} The range, Y = x - 7. what's the answer for this cause I surely don't get it.

y =-9,-8,-7,-6,-5

Step-by-step explanation:

Is this what you need? To find the y values you take an x value and subtract 7. Like the first one -2 would turn into -9

2 or -2

Step-by-step explanation:

If x² - 8x = -12

Step 1

We find x by solving

x² - 8x = -12

We equate to zero

x² - 8x + 12 = 0

We factorise

x² - 6x - 2x + 12 = 0

x(x - 6) -2(x - 6) = 0

(x - 6) (x - 2) = 0

x - 6 = 0, x = 6

x - 2 = 0, x = 2

x = 6 or 2

Step 2

What is x - 4?

When x = 6

= 6 - 4 = 2

When x = 2

= 2 - 4 = -2

Therefore, x - 4 = 2 or -2
