Answer:
x = -1/2
Step-by-step explanation:
To solve the equation, we first need to combine like terms:
Simplify further:
Divide by -12 on both sides to get:
To check the solution, plug x back into the original equation and check if we get the correct answer:
Thus, it checks out and our answer is correct.
x >8
B 1,2,6,7,14
okay
f(x) = 2x³ - 6x² - 48x + 24
relative minimum: (4,-136)
relative maximum: (-2,80)
answer is the second option
