It is known that any exponential function with the form f(x)=a^x is an increasing function while a function of the form g(x)=a^(-x) is a decreasing function.
Furthermore, it a function h(x) is increasing, then the function -h(x) is decreasing. By analogy, if a function k(x) is decreasing, then -k(x) is increasing.
Now let's analyze the functions from the problem.

Since (6/7)^x is increasing and the multiplying factor of 10 is positive, then the function <em>f(x)</em> is also increasing.
Use these rules to find whether each function is increasing or decreasing.
Remember that increasing functions are used to represent growth while decreasing functions are used to represent decay.

D
Step-by-step explanation:
Volume of a cone is (1/3)πr^2h.
You have the necessary info, so just plug it in. (1/3)*π*(3/2)^2*(9/4)
Answer:
Since she read half of the book, it's 50%+ the 40% she read yesterday, that make 90%.So she is left with 10%
