Question

Select "Yes" or "No" to indicate whether the ordered pair is on the graph of the function f(x)=−16x+1 .

Ordered Pairs

Yes No

(0,−16)
(−1,−1)
(1,256)

Answer 1

To determine if the given points are on the graph of the function, substitute the x- coordinate into the equation and if the value is equal to the y-coordinate then it is on the graph

(0, - 16 ) : f(0) = 0 + 1 = 1 ≠ - 16 → No

(- 1, - 1) : f(-1) = 16 + 1 = 17 ≠ - 1 → No

(1, 256 ) : f(1) = - 16 + 1 = - 15 ≠ 256 → No

Answer 2

Answer: The actual correct answer for this are,

(0,-16) = Yes

(-1,-1) = Yes

(1,256) = No

I just took the quiz and this is what I picked and they are correct.
