Lesson 237 of 1524
4.3 Interpreting Using Function Notation
The output value at f(4) is greater than the output value at f(0) because at 4 seconds the drone is 4 meters off the ground while at 0 seconds, the drone is on the ground (0 meters)
Practice this chapterThe output value at f(4) is greater than the output value at f(0) because at 4 seconds the drone is 4 meters off the ground while at 0 seconds, the drone is on the ground (0 meters) The output value at f(2) is equal to the output value at f(5) because at both 2 seconds and 5 seconds, the drone is 4 meters off the ground
Here is a graph that represents function f , which gives the height of a drone, in meters, t seconds after it leaves the ground Decide which function value is greater: f ( 0 ) or f ( 4 )
output value at f(4) — greater than the output value at f(0) because at 4 seconds the drone is 4 meters off the ground while at 0 seconds, the drone is on the ground (0 meters). output value at f(2) — equal to the output value at f(5) because at both 2 seconds and 5 seconds, the drone is 4 meters off the ground.
Be able to describe the connections between a statement in function notation and the graph of the function; use function notation to efficiently represent a relationship between two quantities in a situation; use statements in function notation to sketch a graph of a function.
Worked example
What does “output value at f(4)” mean in 4.3 Interpreting Using Function Notation?
- 1Use the wording this chapter gives for output value at f(4).
- 2The book says: greater than the output value at f(0) because at 4 seconds the drone is 4 meters off the ground while at 0 seconds, the drone is on the ground (0 meters).
- 3Do not use the meaning of output value at f(2). That term means equal to the output value at f(5) because at both 2 seconds and 5 seconds, the drone is 4 meters off the ground.
Result: greater than the output value at f(0) because at 4 seconds the drone is 4 meters off the ground while at 0 seconds, the drone is on the ground (0 meters)
Why. That is the meaning this chapter gives for output value at f(4).
Do not swap output value at f(4) and output value at f(2). output value at f(4) means greater than the output value at f(0) because at 4 seconds the drone is 4 meters off the ground while at 0 seconds, the drone is on the ground (0 meters). output value at f(2) means equal to the output value at f(5) because at both 2 seconds and 5 seconds, the drone is 4 meters off the ground.
