Question

Зная, что g(x) = 2x^3 - 5x/10, найдите g(3)+g(-3)

Answer 1

Ответ:

0

Объяснение:

g(x)=2x³-5x/10

g(3)=2*3³-(5*3)/10=18-15/10=16 1/2

g(-3)=2*(-3)³-(5*(-3))/10=-18+15/10=-16 1/2

g(3)+g(-3)=16 1/2 - 16 1/2=0

Answer 2

To find the value of g(3) + g(-3), we need to substitute x = 3 and x = -3 into the given function g(x) = 2x^3 - 5x/10 and calculate the individual values first.

Let's start with g(3): g(3) = 2(3)^3 - 5(3)/10 = 2(27) - 15/10 = 54 - 1.5 = 52.5

Now let's find g(-3): g(-3) = 2(-3)^3 - 5(-3)/10 = 2(-27) + 15/10 = -54 + 1.5 = -52.5

Finally, we can calculate g(3) + g(-3): g(3) + g(-3) = 52.5 + (-52.5) = 0

Therefore, g(3) + g(-3) equals 0.
