Question
The function 
is defined by 
. What is the value of f(4) ?
- 0
- 2
- 12
- 30
The correct answer is: 2
For a given function f (x), the value of f (4) is calculated by substituting x = 4 in the equation.
Step-by-step solution:-
f (x) = x2 - 5x + 6
f (4) = 42 - 5(4) + 6
∴ f (4) = 16 - 20 + 6
∴ f (4) = 2
Final Answer:-
After substituting x = 4 in the given function, we get f (4) = 2
Hence, Option B i.e. 2 is the correct solution.
