Determine algebraically whether f(x) = x2(x2 + 9)(x3 + 2x) is even or odd.

is an odd function.

Step-by-step explanation:

Let be , by Algebra this expression can be rewritten as:

Where and are even functions, because they satisfy the condition that , whereas is an odd function, as the condition of is observed. Then, the overall function is odd.

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
