Simple, to make it less harder change 4/5 into 0.8
Making the equation,
0.8(15x-5)
Then just multiply:
take 0.8*15(x)=12x
then
0.8*-5=-4
Making the problem, simplified out, 12x-4.
The equation of the function is an exponential function and the key features are Domain: x ≥ 0 and Range: y ≥ 0
<h3>How to interpret the function?</h3>
The equation of the function is given as:
f(x) = 300 (0.70)^x -25
See attachment for the graph of the function f(x) = 300 (0.70)^x -25.
From the attached graph, we have the following key features and interpretation
- Domain: x ≥ 0: The number of hours cannot be less than 0
- Range: y ≥ 0: The amount of blood cannot be less than 0
