Help please with both of these. #9 says find all values of x so that f(x) equal the given value. F(x)=x-8
F(x)=-13

8. y ≤ |x - 3| -1

9. A. -5

Step-by-step explanation:

8. The function: |x - 3| -1, is the function: |x|, translated 3 units to the right and 1 unit down, just like it is seen in the picture.

To know if the shaded area corresponds to

y ≤ |x - 3| -1

or

y ≥ |x - 3| -1

just replace with one point, for example (0, 1) is in the shaded area.

|0 - 3| -1 = 3 - 1 = 2

1 < 2, then:

y ≤ |x - 3| -1 is correct

9. Given:

f(x) = x - 8

f(x) = -13

Then:

x - 8 = -13

x - 8 + 8 = -13 + 8

x = -5

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
