Wich number is between 1/3 and 87/100 on a number line

Any number between 0.33 and 0.87

As you know,  = 0.33

And,

= 0.87

Therefore, the minimum and the maximum points are 0.33 and 0.87. Therefore, you can choose any number, like 0.44, 0.48, 0.36, 0.56, 0.34, 0.86, 0.78 etc.

  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.

f(-2) = -3f(1) = 6 . . . estimated from f(x) = (x+2)^2-3, which matches points on the graph (-1,-2) and (0, 1)

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

the table tells us

g(-2) = 1g(1) = 31

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).

Iam not sure , but probably 750 or 7.5
