What do the words coefficient and constant mean in mathematics?

Step-by-step explanation:

Coefficients are the numbers that come BEFORE a variable, just as 55 is in the term 55x. Constants are numbers in an equation that never change, unless you add them with another constant. For example, in the equation 34x+55=24, the constants are 55 and 24. The only way that either changes is by subtracting the 55 from the 24.

  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).
