f(4) is_______
f(x) = 4 when x is_________

Answers

Answer:

Step-by-step explanation:

x = domain, f(x) = range

Look for matching numbers:

f(4) = 1/2
f(x) = 4 when x = 8

Answers:

f(4) is 1/2

f(x) = 4 when x is 8

====================================

Explanation:

Saying f(4) means f(x) when x = 4.

Locate 4 in the domain bubble. It points to 1/2 in the range bubble. This means x = 4 and y = 1/2 pair up. So f(4) = 1/2.

--------

When we're told f(x) = 4, we're given that y = 4 since y = f(x). So we need to find the x value that gets us to y = 4.

Locate y = 4 in the range. Trace the arrow in reverse to get to x = 8

f(8) = 4

A company offered 200 cameras at a 15% discount during a 5-day saleThe bar graph shows the number of cameras sold at the end of each day.

Day 1 - 30
Day 2 - 40

Answers

Answer:

60%

Step-by-step explanation:

Cameras sold on Day 4 = 25, on Day 5 = 40

The difference in numbers of sold cameras = 40 - 25 = 15

The increase is 15 cameras.

Percentage increase:

15/25*100% = 60%

Answer is60% increase on Day 5 compared to Day 4

There are 6 numbers on a normal dice. What is the probability that if you roll the dice, you'll get a number less than 5?

Answers

There are six numbers on a dice (6 out of 6).
There are 4 numbers on a dice that are below 5 (4 out of 6)
So there is a 4 out of 6 chance (4/6) that you will roll a number less than 5.
