Find critical points by setting derivative equal to 0.
Derivative of polynomial is found by multiplying coefficient by exponent, then subtracting 1 from exponent.
f'(x) = 5x^4 - 30x^2 + 9 = 0
This is in quadratic form, use quadratic formula to find x^2
Answer:
A. The two lines are neither parallel nor perpendicular.
Step-by-step explanation:
Combine Like Terms - same variables with same exponent
6x² - 3x² = 3x²
4x - 9x = - 5x
-12 - -8 = -4
ANSWER: 3x² - 5x - 4
