Question

For a given function g (x) = -5x+ 2x - 1 , evaluate g (2).

  1. -25
  2. 25
  3. 17
  4. -17

Hint:

g (x) = -5x+ 2x - 1
g(2) = -5(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) = -5x+ 2x - 1.

    Hence, the value of g (2) for the given function g (x) = -5x2 + 2x - 1 is -17.
