Answer: It's -0.5 when substitute the value of x into the right side and solve
Note this answer is from someone else.. I came here for the same question lol
Answer:
4x + 18
Step-by-step explanation:
This is called a composite function, meaning passing the range of one function as a domain of another function.
For f(f(x)), the inner-function's range is passed as the domain of the outer function.
We can do so by substitution,
The range of f(x) can be written as 2x + 6 for any defined x values,
So we will substitute 2x + 6 as the 'x' of another function which is in this case
f(x) again, so it looks like this 2(2x+6) + 6 which can be simplified into
4x + 18
Answer:
It cannot be extended.
Step-by-step explanation:
Consider the function . To extend this functions so it is continous at (0,0) we must define . However, this implies that the limit exists. So, we should find if the limit exists or not.
In this case, consider the case in which y =0. When y=0 then
But, when x=0, we get
.
So, since the limit depends on how we approach to the point (0,0) the limit does not exist. So we can't extend f(x,y) so it is continous.
Answer:
D) output increases from 200 to 300 units
Step-by-step explanation:
The marginal cost is the slope of the cost curve. You can see from a graph that it is a minimum between 200 and 300 units.
Answer:
The quotient rule means dividing
Step-by-step explanation:
"The quotient rule says that if we have exponents with the same base being divided, we can just subtract the exponents. Ultimately this is about <u>dividing</u> exponential expressions."
