Sendo a função f(x) = 4x³ +8x² - 2 . x + 13, determine o valor de 9.f (3)

The value of 9f(3) is 1683.

Step-by-step explanation:

This is a compound function, so let's call it , where it is equal to:

To solve it, we need to find and apply it on the expression above, this is done below:

Applying it on we have:

1,863

Step-by-step explanation:

First thing to do here is to substitute 3 for the value of x

f(3) =4)3)^3 + 8(3)^2 -2(3) + 13

= 4(27) + 8(9) -6 + 13

= 108 + 72 + 7 = 207

we now multiply this result by 9

= 9 * 207 = 1,863
