x ≤ -4 or x ≥ -1

interval

(-∞,-4] U [-1,∞)

Step-by-step explanation:

f(x) = √(x² + 5x + 4)

domain

√(x² + 5x + 4) ≥ 0       / ^2

x² + 5x + 4 ≥  0

(x + 4)(x + 1) ≥ 0

x + 4 ≥ 0

x + 4 = 0

x = -4      Value

x + 4 < 0

x < - 4     Value

x + 4 > 0

x > -4      Not value

x + 1 = 0

x = -1      Value

x + 1 < 0

x < - 1     Not value

x + 1 > 0

x > -1      Value

x < - 4 or x = -4  or x >  -1 or x = -1

x ≤ -4 or x ≥ -1

interval

(-∞,-4] U [-1,∞)

it would open into a square depending on the type of envelope i’m not sure about the second part

i think the answer is true
