We have been given a function
. We are asked to choose the point from given choices, which is not a solution of given function.
Let us check each given point one by one.
A. (3,9)




Since both sides of function are equal, therefore, point (3,9) is the solution of our given function.
B. 




Since both sides of function are equal, therefore, point
is the solution of our given function.
C. 




Since both sides of function are equal, therefore, point
is the solution of our given function.
D. 




Since both sides of function are not equal, therefore, point
is not a solution of our given function and option D is the correct choice.
Answer:
(-4 , 1)
Step-by-step explanation:
We know that the turning point of any parabola is in its vertex. The x of the vertex can be calculated with the formula:
x = -b/2a
In our case b = 8, a = 1, so:
x = - 8/2 = -4
We plug this value into our original equation and find the y of the vertex:
(-4)^2 + 8(-4) + 17 = 16 - 32 + 17 = 1
Vertex = (-4 ; 1)
Plugging in (5 weeks, 40 loads) and (10 weeks, 30 loads) into each choice indicates that f(x) = -2x + 50 is the only correct answer.
