An exponential function has a graph that is a smooth curve; it either increases at an ever increasing rate or decreases at an ever increasing rate. The only graph that fits these characteristics is the first one.
Answer:

Step-by-step explanation:
Applying the chain rule

Then it becomes

In x=0
f}{dx} =-\frac{df}{dx}[/tex]
Then

The answer is c y=3x-1 if you just plug in the numbers you can see if it is equal
Answer:
B
Step-by-step explanation:
y - y1 = m (x - x1)
y1 = 3
x1 = 5
m(the slope)= -12
