Question
If f(x) = x2 - 2 , g(x) = -2x , evaluate f (g(1))
- -4
- -2
- 2
- 4
The correct answer is: 2
To find the value of f (g(1)) for the given functions f(x) = x2 - 2 and g(x) = -2x .
Given f(x) = x2 - 2 , g(x) = -2x
g(1) = -2 × 1 = -2
f(g(1)) = f(-2) = (-2)2 - 2 = 4 - 2 = 2
The value of f (g(1)) for the given functions f(x) = x2 - 2 and g(x) = -2x is 2.
