Given that f(x)=2(x−3)2−8, determine the true statement. The range of f(x) is y≥−8.

The graph of f(x) is decreasing from (3,∞).

The domain of f(x) is x≥3.

The graph of f(x) has a maximum point at (3, -8).

answer: ur v dumb

the volume is 1/3 a^2h.

try quizlet : ) hope this

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
