Answer: Direction opens downward
Step-by-step explanation:
X-Intercept: (1/14,0),(-1/4,0)
Y-Intercept: (0,1)
Find the vertex using x= -b/2a
Plug it into the vertex form = y=a(x-h)^2 +k
H,K will identify the direction.
Answer:
or 
Step-by-step explanation:
the given function is;
According to the rational roots theorem, the possible rational roots are;
.
According to the Remainder Theorem, if 
, then 
is a zero of the polynomial.
Also,
Therefore the other roots are;
When log2 3 = d is turned to exponential form it is 2^d = 3
then do algebra where d = 3/2
d = 1.5
log2 3 = 1.5
then log2 72 = 1.5 squared + 3
log2 72 = 5.25
It is b 70 because in a quadrilateral the angles have to equal 360 and 85 + 150 + 55 equals 290 360 - 290 is 70
