Question

F(x)=1/3x^3+1/2x^2-2x , x0=3

Answer 1

Ответ:

7.5

Объяснение:

1) Подставить вместо х 3:

$\frac{1}{3} \times ({3})^{3} + \frac{1}{2} \times( 3) {}^{2} - 2 \times 3 = \frac{15}{2} = 7.5$

Answer 2

To find the value of the function F(x) at x0 = 3, simply substitute x0 into the expression for F(x) and perform the calculation. Here's how you can do it:

F(x) = (1/3)x^3 + (1/2)x^2 - 2x

x0 = 3

F(3) = (1/3)(3)^3 + (1/2)(3)^2 - 2*(3)

Now, let's perform the calculations step by step:

F(3) = (1/3)(27) + (1/2)(9) - 6

F(3) = 9 + 4.5 - 6

F(3) = 7.5

Therefore, when x = 3, the value of the function F(x) is 7.5.
