A piecewise function’s graph is broken up into different pieces or parts where each part of the graph has different functions. In order to make use of this they ask to solve when x = 3. In the piecewise functions above on the right side it gives for what values of x that piece graph covers on a coordinate plane.
In your case, you would need to use
x is greater than or equal to 1, since 3 is greater than 1 and the other options wouldn’t work for x = 3.
Then look left of x is greater than or equal to 1 and apply the rule to your x value of 3. This is x + 1. Which is
3 + 1 = 4. Which makes 4 the answer.

2. never

3 .08c = 7.50+.05c 250 pages

step-by-step explanation:

1. sometimes

the theoretical probability of rolling a 1 is 1/6. perhaps you got really lucky and never rolled a 1 in those 60 times. your experimental probability is 0. or perhaps you rolled a 1 20 times. your experimental probability is 20/60 is 1/3. it really just depends on how you rolled in that experiment.

2. never

the probability of the event occurring is 1. that is being 100 % sure it will happen. that is the maximum amount of confidence we have.

3. no customer card cost: .08 times number of pages

customer card cost: 7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250

the cost is the same at 250 pages
