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
To find the total cost, you need to add these numbers together
you get 7.37 as your answer, but you need to round this to the nearest whole number.
rounding 7.37 will make it 7.
the total cost is about $7
