Me asap im timed the graph above reprenets a function what is the value of f(4)?

f(4)=0 because when x=4, y=0.

f(4) is the X value, so you need to find what Y is when X is 4.

When the graphed line crosses X4, the line is on the Y axis, which would be zero.

F(4) = 0

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

answer: b
