Answer: B) [1.5, ∞)
Step-by-step explanation:
log₈ (4x + 2) + 4 ≥ 5
log₈ (4x + 2) ≥ 1 subtract 1 from both sides
4x + 2 ≥ 8¹ apply log rules
4x ≥ 6 subtracted 2 from both sides
x ≥ 1.5 divided 4 from both sides
In interval notation: [1.5, ∞)
1.5 is included so use the bracket.
It is "greater than" so it goes to infinity (which uses a parenthesis)
