Use the table to determine the appropriate model of the function, x 0 1 2 3
4 f(x) 3 7 29 87 199 linear quadratic cubic exponential
1 answer:
Points Lying on the undefined curve are
x : 0 1 2 3 4
f(x): 3 7 29 87 199
Plotting the points on the coordinate plane
As you will see, the value of x increases , value of y increases .
It is not linear, because slope between two points is not same.
Neither quadratic nor cubic , it is not cutting x axis .
So, As value of x increases, value of y does not increases by a fixed quantity, but it increases.
So, option (D) Exponential ,Function word is the right word Describing these points.

The total amount paid for vase is $ 41
<em><u>Solution:</u></em>
Given that
Cost of vase = $ 34.99
Shipping charge = 3 dollars
Sales tax = 8.25 % was paid on the subtotal which included the shipping charge
To find: total amount paid for vase
total amount paid for vase = Cost of vase + Shipping charge + sales tax
Let us first find the sales tax
Given that 8.25 % was paid on the subtotal which included the shipping charge
Subtotal = 34.99 + 3 = 37.99
So 8.25 % of 37.99 was paid as sales tax
Therefore sales tax amount paid = $ 3.1341
total amount paid for vase = Cost of vase + Shipping charge + sales tax
total amount paid for vase = 34.99 + 3 + 3.1341 = 41.1241 ≈ 41
Therefore total amount paid for vase is $ 41
