Evaluate the function \( f(x) = 5x^3 + 27x^2 - 13x + 30 \) at \( x = -6 \).

A. \( f(-6) = 810 \)
B. \( f(-6) = 210 \)
C. \( f(-6) = -210 \)
D. \( f(-6) = -810 \)

Answer :

Final answer:

In the function f(x) = 5x^3 + 27x^2 - 13x + 30, for the value x = -6, none of the options available provide the correct answer according to our calculations. The student should verify the question or the choices provided.

Explanation:

The question is asking to find the value of the function f(x) = 5x^3 + 27x^2 - 13x + 30 at x = -6. We first substitute -6 into the function:

f(-6) = 5*(-6)^3 + 27*(-6)^2 - 13*(-6) + 30.

By simplifying the expression we have f(-6) = 5*(-216) + 27*36 + 78 + 30.

So, f(-6) = -1080 + 972 + 78 + 30

Therefore, f(-6) = 0.

None of the options provided in the question (A) f(-6) = 810 B) f(-6) = 210 C) f(-6) = -210 D) f(-6) = -810) match the solution we calculated. Therefore, there may be a typo in the question, or one of the options provided is incorrect.
