This needs to be graphed, please help!

Step-by-step explanation:

x = 0

y = | 0 + 4 | - 1

y = 4 - 1

y = 3

y = 0

0 = | x + 4 | - 1

1 = | x + 4 |

x + 4 = 1 => x₁ = 1 - 4 => x₁ =  - 3

x + 4 = - 1 => x₂ = - 1 - 4 => x₂ = - 5

or

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
