hi,
the function is given with it's canonic form.
canonic form is : f(x) = a ( x-α)² + β
α and β are the value of the coordonnates of the vertex.
so here we have : ƒ(x) = 2(x−1)² +3
with α = 1 and β = 3
so vertex is V (1;3)
So yes, answer is A.
3/6 divide numerator and denominator by 3 and get 1/2
12/20 divide the numerator and denominator by 2 ,and get 6/10 divide by 2,and get a final answer of 3/5.
8/24 divide the numerator and denominator by 8 ,and get 1/3.
30/40 divide the numerator and denominator by 10 ,and get 3/4
I hope this helps you,and good luck.
6 be cause 8 times 6 equals 48
I think its -40 because it looks like you have negative 40 then ur adding 10
sry if my answer is wrong but I think it is the square root of nine
