Web13 dec. 2024 · • f(x) = x + 5 • f(2g) = 19. To find: • The value of f(3 – g) Approach and Working: • f(x) = x + 5. Putting, x = 2g in the above equation, we get, • f(2g) = 2g + 5, which is given as 9 • Thus, 2g = 19 – 5 = 14. o Implies, g = 7 • Now, f(3 – g) = f(3 – 7) = f(-4) = -4 + 5 = 1. Hence, the correct answer is Option B Answer: B WebSOLUTION: If f (x)=x2-kx-3 and f (2)=9, then k = Algebra: Evaluation of expressions, parentheses Solvers Lessons Answers archive Click here to see ALL problems on …
