So a function is basically the x values don't repeat with any differnt y values (x,y)
the first number should never repeat with a differnt y value
A. 1 repeats with2 and 4, not a function B.. no repeat, it's a function C. 4 repeats with 2 and -2,not a function D. 5 repeats with 0 and 3, not a function
A General Note: The Product Rule for Simplifying Square Roots. If a and b are nonnegative, the square root of the product a b \displaystyle ab ab is equal to the product of the square roots of a and b.
It will take 8 seconds for all of the dominoes to fall over.
This will be an exponential function. To find the growth rate, we can write out the terms of the sequence that goes along with it: 10, 20, 40, ...
"Growth rate" is the same as percent of increase or decrease. We find the amount of increase and divide by the original amount: 20-10 = 10 increase; 10/10 = 1.
The exponential function is of the form f(x) = a*(1+r)ˣ, where a is the initial value (10), r is the growth rate (1), and x is the number of time periods. Using the variables given to us in the problem along with this information, we have:
