Difference quotient: $\frac{f(x+h)-f(x)}{h}$ = 2

Step-by-step explanation:

The difference quotient is the word that we use when trying to calculate the average rate of change of the function over a specific interval, which in this case, is h.

The formula for calculating the difference quotient is:

$\frac{f(x+h)-f(x)}{h}$

In order to determine the difference quotient of the function f(x)=2x-5 we need to first evaluate f(x+h) of this function.

We can do so by substituting x + h for x into the function.

Distribute 2 inside the parentheses.

Now that we have found f(x + h), we can use the formula for the difference quotient and substitute f(x + h) and f(x) into it:

$\frac{(2x+2h-5)-(2x-5)}{h}$

Distribute the negative sign inside the parentheses.

$\frac{2x+2h-5-2x+5}{h}$

Combine like terms in the numerator. The 2x and 5's cancel out. We are left with:

$\frac{2h}{h}$

The h's cancel out, and this simplifies to:

The difference quotient of f(x) is 2.

Answer from: Quest

the answer is 200

step-by-step explanation:

this is a problem about poisson probabilities. i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.

here's how you can see a poisson distribution coming. when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution. this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot. there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything. the form of the distribution is

probability of n chips = {[e^(-x)]*(x^n)} / (n! )

Answer from: Quest

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.

therefore, the correct answer is d.

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
