Question
For a given function g (x) = -5x2 + 2x - 1 , evaluate g (2).
- -25
- 25
- 17
- -17
Hint:
g (x) = -5x2 + 2x - 1
g(2) = -5(2)2 + 2 × 2 - 1 = -5 × 4 + 4 - 1 = -20 + 4 - 1 = -17
The correct answer is: -17
To find the value of g (2) for the given function g (x) = -5x2 + 2x - 1.
Hence, the value of g (2) for the given function g (x) = -5x2 + 2x - 1 is -17.
