Answer:
3) 10
4) 12
hope that helps buddy
Step-by-step explanation:
This is an exponential function.
Without any transformations (up or down), the range is y > 0
So we factor 12
remember that (-) times (-)=(+)
and
(-)+(-)=(-) so therefor the factors must be negative
factor 12
2,2,3
we have
-2 times -6 which adds to -8
-3 times -4 wihch adds to -7
the numbers are -3 and -4
Answer:
a=sqrt(d)-b, a=-sqrt(d)-b
Step-by-step explanation:
(a+b)^2=d
(a+b)=sqrt(d)
a+b=sqrt(d), a+b=-sqrt(d)
a=sqrt(d)-b, a=-sqrt(d)-b
