Answer:
therefore y= - (x-2)^2 + 5
Step-by-step explanation:
u do this by using this format here ..,
y=a(x-h)^2+k
sub in the vertex points as h=2 and k = 5 , since the 2 is positive its sign will be -2 in the brackets because when solving for x-2=0 it is x=2
y=a(x-2)^2+5
then with your (0,1) points plug that in as y and x
1=a(0-2)^2+5
1=a(-2)^2+5
1=4a+5
1-5=4a
-4=4a
a=-1
therefore y= - (x-2)^2 + 5
The inputs are -3, -4, 8, and 7
Answer:
-76/8 = -19/2
In an arithmetic sequence, the nth term, an, is given by the formula:
an = a1 + (n - 1)d, where a1 is the first term and d is the common difference.
So, a9 = a1 + 8d
Substituting in the given data, 12 = 88 + 8d
-76 = 8d
d = -76/8 = -19/2
