Given:
Year 0 = 2005 = 90,000
Year 1 = 2006 = 91,200
(91,200 - 90,000)/90,000 = 1,200/90,000 = 0.013
f(x) = 90(1.013)x
f(1) = 90(1.013)1
f(1) = 91.170
The second option, f(x) = 90(1.013)x, is the best representation of the relationship between x and f(x).
Scientific notation
Explanation:
…
When raised to the third power, it is the number times itself three times.
-2(-2) = 4
4(-2) = -8
<span>f(x) = 4x + 3
g(x) = -2x + 5
(f o g) (5) means the function of g when g is a function of 5
(the function of the function concept)
so we need to get g(5) firstly
</span>
<span>g(x) = -2x + 5
g(5)= -2(5) + 5 = -5
After that, f(g(5)) = f(-5) = 4(-5) + 3 = -20 + 3 = -17
I hope that helps
