Answer:

B. (–2, 18), (0, 10), (2, 2)

Step-by-step explanation:

Find the function by taking the integral of the derivative.

F ( x ) = 10 x − 2 x 2 + C

Given: f(x) = 10 - 4x

Just substitute in each points to see if they satisfy the equation.

Looking (c)  

(-2,18) ----> 10 - 4(-2) = 10 + 8 = 18.  (-2,18) is satisfied.

(0,10) ----> 10 - 4(0) = 10. (0,10) is satisfied.

(2,2) ----> 10 - 4(2) = 10 - 8 = 2. (2,2) is satisfied.

Therefore, (b) is the solution.
