The axis of symmetry for the graph if the function is f(x)=1/4x^2 + bx + 10 is x=6. what is the value of b?

b= -3

Step-by-step explanation:

y=x²/4+bx+10=1/4(x²+2*2b+4b²)+10-b²

=(1/4'x+2b)²+10-b²

==>-2b=6==>b=-3

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
