Question

Which points are on the graph of the function rule f(x) = 10 – 4x?

Answer 1

(–2, 18), (0, 10), (2, 2)

Answer 2

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)
