Q:
The axis of symmetry for the graph of the function is f(x) = 1/4 x2 + bx 10 is x = 6. what is the value of b?
Accepted Solution
A:
Answer:Step-by-step explanation:f(x) = 1/4 x²+bx+10the derivate is : f'(x) = 1/2 x +byou have : f'(6)=01/2 (6)+b=03+b =0b = -3so f(x) = 1/4 x²-3x+10.......f(6) =1/4(6)² -3(6)+10 =9-18+10 =1f(x) = 1/4(x-6)²+1... the vertex form
