Answer:
Step-by-step explanation:
f(x) = a(x-p)(x-9) is the equation of a vertical parabola.
If a>0, the parabola opens upwards.
If a<0, the parabola opens downwards.
Also, the focal length of the parabola is 1/|4a|.
Answer:
do u want me to get u the answers to the whole book?
Step-by-step explanation:
i can do that...
You can find the critical numbers by finding the derivative of the function and solving for 0.
F(x) = x(4/5)(x-6)(2) = x(8/5)(x-6) = (8/5)(x^2 - 6x)
Taking the derivative:
F'(x) = (8/5)(2x - 6)
F'(x) = 0 at x = 3,
critical number = 3
