Expand
x²+6x-27=-27
add 27 both sides
x²+6x=0
factor
x(x+6)=0
set to zero
x=0
x+6=0
x=-6
x=0 or -6
answer is 0 since -6 is not listed
Answer:
growth
Step-by-step explanation:
Exponential function represents f (x) = a ^ x
First, the derivative is f '(x) = xa ^ (x-1)
Because when a is greater than 1
(1.08>1)
The values of derivative functions are all greater than 0, so they are monotonically increasing in the domain of definition
So when the base number is greater than 1, it is an increasing function
And the larger the index, the larger the number
I hope it can help you
