What is the answer pls

8.89 gallons per hour

Step-by-step explanation:

In order to find the rate of change, you need to find the slope of the graph.

To find the slope, you use equation (y2 - y1 ) / (x2 - x1)

The given coordinates are:

(0 hours, 0 gallons)

(4.5 hours, 40 gallons)

Next, plug in the x and y values into the slope equation:

y2 = 40 gallons

y1 = 0 gallons

x2 = 4.5 hours

x1 = 0 hours

Slope = (40 - 0) / (4.5 - 0) = 40 gallons / 4.5 hours = 8.888889 gallons per hour

round to 8.89

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.
