Q. f(x)=x3+2x+7 f(x)=x^{3}+2 x+7 \newlineThe function f f is defined. What is the value of f(3) f(-3) ?\newlineChoose 11 answer:\newline(A) 26-26\newline(B) 14-14\newline(C) 1010\newline(D) 4040
  1. Evaluate f(x)f(x) at 3-3: We need to evaluate the function f(x)f(x) at x=3x = -3. The function is given by f(x)=x3+2x+7f(x) = x^{3} + 2x + 7. Let's substitute xx with 3-3 and calculate the value.\newlinef(3)=(3)3+2(3)+7f(-3) = (-3)^{3} + 2(-3) + 7\newlinef(3)=276+7f(-3) = -27 - 6 + 7
  2. Substitute and Calculate: Now, let's perform the arithmetic operations to find the value of f(3)f(-3).f(3)=276+7f(-3) = -27 - 6 + 7f(3)=33+7f(-3) = -33 + 7f(3)=26f(-3) = -26
