Answer:
2 real roots
Step-by-step explanation:
The discriminant is b^2 -4ac where ax^2 +bx -c
If b^2 -4ac > 0 we have 2 real roots
b^2 -4ac = 0 we have 1 real root
b^2 -4ac < 0 we have 2 complex roots
x²-x-12=0
a =1 b=-1 c = -12
(-1)^2 - 4(1)*(-12)
1 +48
49 > 0
2 real roots
Function F slope : 6/8 or 3/4
Function G slope : 3/5
Ans : I think it's 3/4 cuz it's greater in value than 3/5.
(Sorry if I'm confusing.)
B. Yes it's an exponential function because the y is increasing rapidly without a constant rate of change
48 hours because you times 24 by 2.
