Question

For j(x) = 5x − 3, find j of the quantity x plus h end quantity minus j of x all over h.

Answer 1

We will see that the difference quotient of the given function is 5.

How to find the difference quotient?

Here we want to find the difference quotient for the given function.

First, remember that the difference quotient is given by:

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

Now we want this for the function:

j(x) = 5x - 3

Then we will have:

$\lim_{h \to 0} \frac{j(x +h) - j(x)}{h}\\\\\lim_{h \to 0} \frac{5*(x + h) -3 - 5*x + 3}{h}\\\\\lim_{h \to 0} \frac{5x + 5h - 3 - 5x + 3}{h}\\\\\lim_{h \to 0} \frac{5h}{h} = 5$

So the difference quotient of j(x) is 5.
