What is it that we need to find?
we have given the values of x and f(x) in the table we have x=2 and f(x)=5 for this if we plug x=2 in option f(2)=2^2+1=4+1=5.
for f(3)=2^3+1=8+1=9.
f(4)=2^4+1=16+1=17 .so the exponential function modelled by the table is option B)f(x)=2^x+1.
In order to find CPU (Cost per unit) we must take the cost, and divide it by the number of units.
So,

Since we are talking about money, it is implied to round to the nearest cent, so the final answer is
$3.44
Answer:
27/220.
Step-by-step explanation:
To get £2.50 Pita has to take two pound coins and one 50p coin.
The probability of picking £1 then £1 then 50 p = 3/12 * 2/11* 9/10
= 9/220.
The number of possible arrangements of 2 pounds and 1 50p
= £-£-50, £-50-£ and 50-£-£.
= 3
So the required probability = 3 * 9/220
= 27/220.
