The expression 2x+50 represents the elevation above sea level, in meters, of a rock climber after x minutes of climbing.
which is the rock climbers initial height above sea level?
enter your answer in the box.

The rock climbers initial height above sea level is:

                                 50 meters.

The expression which is used to represent the elevation above sea level, in meters, of a rock climber after x minutes of climbing is given by:

                                     2x+50

Now, we are asked to find the rock climbers initial height above sea level i.e. we are asked to find the value of the expression when x=0.

Hence, when x=0 we  have:

2x+50=2×0+50

          = 50

Hence, the answer is: 50 meters.

  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).
