If f(x) = 2x2 + bx + c, find the value of "c" that makes the vertex of the given graph the same as the vertex of f(x).

A.) 24
B.) 56
C.) 75
D.) 90

75

Use x =  

−b

2a

→ 6 =  

−b

2(2)

→ b = −24. Use the point (6, 3) in the function f(x) = 2x2 + bx + c → 3 = 2(6)2 −24(6) + c → c = 75

Step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
