If f(x) = 2x squared - 1x - 4, find f(1).
A.
4
B.✓ Correct
-3
C.
12
D.
9
Detailed Explanation
Choice B is the best answer. f(1) = 2(1) squared - 1(1) - 4 = -3
Why others are wrong:
A: 4 is incorrect because it does not satisfy the equation.
C: 12 is incorrect because it does not satisfy the equation.
D: 9 is incorrect because it does not satisfy the equation.
