Answer:

Jake

Step-by-step explanation:

The average rate of change is distance divided by time. You want both of their rates in feet per second. 60 feet divided by 10 seconds is 6 feet per second. 25 feet divided by 5 seconds is 5 feet per second. 6>5

Given f (x) = x2 + 5x + 6, what is f of the quantity 2 plus h end quantity minus f of 2 all over h equal to?

scoray [572]

We want to get the difference quotient for the given function, we will get see that the difference quotient is equal to:

f'(x) = 2x + 5

<h3>The difference quotient:</h3>

For a given function f(x), we define the difference quotient as:

$\lim_{h \to 0} \frac{f(x + h) - f(x)}{h}$

In this case, we have:

f(x) = x^2 + 5x + 6

Replacing that in the difference quotient we get:

$\lim_{h \to 0} \frac{(x + h)^2 + 5*(x + h) + 6 - x^2 - 5x - 6}{h}\\\\\lim_{h \to 0} \frac{x^2 + 2xh + h^2 + 5*x + 5*h + 6 - x^2 - 5x - 6}{h}\\\\\lim_{h \to 0} \frac{ 2xh + h^2 + 5*h }{h}\\$
