Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
(A) $f(x) = -|x+1|+3$
maximum value is 3 when $x = -1$
(B) $f(x) = (2x − 1)^2 + 5$
minimum value is 5 at $x = \frac{-1}{2}$
(C) $f(x) = 6 – x^2$
maximum value is 6 at x = 0
(D) $f(x) = x^3 + 1$
This function is always increasing ⇒ No maximum value
