Graphing exponential function in exercise ,sketch the graph of the function. see example 3 and 4.
y = -2x

Check the table and the graph below

Step-by-step explanation:

1) To graph this function, make a table with 2x1 , for x and y values. Assign any value for x, then plug into the function to find y.

2) Mark on the x-axis each x-coordinate and its correspondent, then draw the curve.

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.

54.864 meters
