The base of the exponential function must be a positive number, then option C. it's not possible.
In the graph, when x=0, y=3
Option B it's not posiible because when x=0→F(0)=3^0→y=1
In the graph, when x=1, y is approximately 4
Option A it's not possible because when x=0→F(0)=3*(0.4)^1=3*0.4→y=1.2
It's option D, because when x=0→F(0)=3*(1.4)^1=3*1.4→y= 4.2
Answer: OPtion D. F(x)=3*(1.4)^x
Answer:
The total cost is $16.96
The cost per photo is $1.06
Step-by-step explanation:
Hello!
<h3><u>
Part 1:</u></h3>
1 roll of film costs $4.79. 1 roll of film has 16 photos. To develop the 16 photos, you need to pay $12.17.
First, let's find the total cost for the film and the development for 1 roll of film:
- Total Cost = Cost of Film + Cost of developing
- Total Cost = $4.79 + $12.17
- Total Cost = $16.96
<u>The total cost of 16 photos is $16.96</u>
<u />
<h3><u>Part 2:</u></h3>
Now, we have to find the price per picture on the roll of film. We know that there are 16 shots on the film, so we can simply divide the total price by 16 to find the price per picture.
Divide:
- $16.96 ÷ 16
- ($16 ÷ 16) + ($0.96 ÷ 16)
- $1 + $0.06
- $1.06
<u>The price per photo is $1.06</u>

Answer:
A
Step-by-step explanation:
this is because a range is simply a collection of numbers that can be found in the domain
and since there is no domain, we assume that the numbers are all in the domain
leading us to our answer a
