Step-by-step explanation: i am 100% sure
The answer is B for increase of one year the events increase by 0.5
You can do this by using the eqn
y=0.5x-1.3
y=0.5(15)-1.3
y = 7.5-1.3
y = 6.2
y=0.5(16)-1.3
y=8-1.3
y=6.7
6.7-6.2 = 0.5
Answer:
See attachment
Step-by-step explanation:
Assuming the equation is

Then we have a transformed exponential function whose parent function is

We can see that:
There is a transformation of the form:

The parent function has been shifted to the right 4 units and down 3 units.
The is shown in attachment.
