Answer:
a = 8, b = 
Step-by-step explanation:
Given the exponential function
f(x) = a
To find a and b use the given coordinate points on the graph
Using (0, 8 ), then
8 = a
[
= 1 ] , then
a = 8
f(x) = 8
Using (2, 18 ) , then
18 = 8b² ( divide both sides by 8 )
= b² , that is
b² =
( take the square root of both sides )
b =
= 
Thus
f(x) = 8
Annual growth rate is (1+0.15)^12. or 5.35025 or 535.025%
Answer:
y=5x+25
y=5(12)+25
y=85
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
5(2x-3)=15
10x-15=15
10x=30
x=3
