Answer:
Option B is the answer
Explanation:
To find the ordered pair which lies on the graph f(x) = -2x²
We will put the value of ordered pair in the function
If it satisfy the function then par will lie of the graph.
f(x) = -2x²
Option (A) (1,-4)
f(1) = -2 (1)² = -2 ≠ (-4)
Pair does not lie on the graph
Option B. (1, -2)
f(1) = -2
Pair will lie on the graph
Option C. ( 1, 4 )
f(x) = -2 ≠ 4 so pair will not lie in the graph
Option B is the answer
