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.

a 10 percent increase

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
