Question

Let f(x) be a continuous function such that f(1)=2 and f(x)= x³ + 6 and What is the value of f(5)?

(A) 11.446
(B) 13.446
(C) 15.446
(D) 24.672
(E) 26.672

Answer 1

To calculate f(5) for the function f(x) = x³ + 6, substitute 5 for x to get f(5) = 5³ + 6 = 131. None of the options given match this value, implying an error in the question or options.

Step-by-step explanation:

To find the value of the function f(x) at a particular point, we simply substitute the value of x into the function's formula. Since we are given that f(x) = x³ + 6, we can find the value of f(5) by substituting x with 5.

Therefore, f(5) = 5³ + 6 = 125 + 6 = 131.

Among the options provided, none match the correct value of 131. It seems either the function provided is incorrect, or the options given are mistaken. However, based on the information provided, f(5) should be 131.
