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) = x^{2} - 5x + 6

f (4) = 4^{2} - 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.
