Find and simplify the difference quotient f(x + 1) – f(x) for the following function.

ra1l [238]

In your situation you said that

$f(x) = mx+b$
$m=0$

Putting those together, you'd have $f(x) = b$ because $0\cdot x+b=b$ .

To evaluate the difference quotient, first find each piece on it's own:

$f(x+1) = b$ because $f(x) = b$ no matter what your x-value is.
$f(x) = b$

So putting those together:

$f(x+1) - f(x) = b-b = 0$

Remember that the difference quotient is basically finding the slope of something. Since you were given that the slope is 0, the difference quotient should work out to match that.

Answer:

The volume of the irregular figure would be 144 $cm^3$ .

Step-by-step explanation:

If you wish to make the process of calculating the volume easier, you can picture the irregular figure as two rectangular prisms: the large one on the bottom, and the smaller one appearing to protrude from the prism below it. Using this method, you only need to find the volumes of the two rectangular prisms and add the values together to get the volume for the irregular figure. The formula used to find the volume of a rectangular prism is $l*w*h$ , where $l$ , $w$ , and $h$ , represents the length, width, and height of the rectangular prism respectively. Using the formula above, the volume of the larger rectangular prism would be 12 * 3 * 3 = 12 * 9 = 108 $cm^3$ , and the volume of the smaller rectangular prism would be 4 * 3 * 3 = 12 * 3 = 36 $cm^3$ . So the volume of the entire irregular figure would be 108 + 36 = 144 $cm^3$ .
