Answer with Step-by-step explanation:
we are given that:
f(x)=10-4x
We have to determine which points lie on the graph of f(x)
1. (2, –18), (0, –10), (–2, –2)
When x=0
f(x)=10
But here we are given (0,-10)
Hence, this option is incorrect
2. (18, –2), (10, 0), (2, 2)
When x=10
f(x)= -30
but here we are given (10,0)
Hence, this option is incorrect
3. (–18, 2), (–10, 0), (–2, –2)
when x= -10
f(x)= 50
but here we are given (-10,0)
Hence, this option is incorrect
4. (–2, 18), (0, 10), (2, 2)
f(-2)=18,f(0)=10 and f(2)=2
Hence, Correct option is:
(–2, 18), (0, 10), (2, 2)
