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}\\

Now we can cancel the factor h to get:

\lim_{h \to 0}  2x + h + 5 = 2x + 0 + 5 = 2x + 5

So the difference quotient is equal to 2x + 5.

The width of rectangular field is x metres.
olga2289 [7]

Answer:

Possible values of x are   50 < x < 110.

Step-by-step explanation:

Consider the perimeter of the field:

2x + 2(x + 30) < 500

2x + 2x + 60 < 500

4x < 440

x < 110.

Consider the area of the field:

x(x + 30 ) > 4000

x^2 + 30x - 4000 > 0

(x - 50)(x + 80) > 0

The critical values are x = -80 and 50.

As x is a width it must be positive so x > 50.

This graph shows the solution to which inequality?
telo118 [61]

Answer:

y > \frac{1}{3}x - 2

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

y = mx + b

In which m is the slope, and b is the y-intercept(value of y when x = 0).

In this question:

We have that when x = 0, y = -2. So the line is given by:

y = mx - 2

Finding the slope:

We have two points in the line, which are (-3,-3) and (3,-1). The slope is given by the change in y divided by the change in x. So

Change in y: -1 - (-3) = -1 + 3 = 2

Change in x: 3 - (-3) = 3 + 3 = 6

Slope: m = \frac{2}{6} = \frac{1}{3}

Solution to the inequality:

The solution to this inequality is all the points above the dashed line, which means that the dashed line is not part of the solution. So

y > \frac{1}{3}x - 2
