the 1 is the h and the -2 is the k
f(x) = a(x - h)^2 + k
f(x) = a(x-1)^2 -2
to find a substitute x=3, y=6 in
6= a(3-1)^2 -2
6 =a *2^2 -2
add 2 to each side
8 = 4a
a =2
f(x) = 2(x-1)^2 -2 this is the vertex form
distribute to get the standard from
f(x) = 2(x^2-2x+1) -2
2x^2 -4x+2-2
f(x) =2x^2-4x is the standard form
Choice A
Answer:
0.301
Step-by-step explanation:
Given that log 3 = .477 and log 6 =.778
Log 2
= log(6/3)
= log 6 - log 3
= 0.778 - 0.477
= 0.301
Hence the value of log 2 is 0.301
Answer
$22
Step-by-step explanation:
This is the answer because if we take 3 2/3 into a mixed number, it would be 11/3. If you multiply 11 to 6, you would get 66 and divide it by 3, and get 22.
