The graph of y=f(x) is shown above. Which of the following could be the graph of y=f′′(x)?.

AfilCa [17]

The true statement about the graph of f(x) is $f(x) = \frac 35x + 3$

The graph of f(x) is a straight line that passes through the points (-5,0) and (0,3).

Start by calculating the slope (m)

$m = \frac{y_2 - y_1}{x_2 -x_1}$

So, we have:

$m = \frac{3-0}{0--5}$

Simplify

$m = \frac{3}{5}$

The equation of the line is then calculated as:

$y = m(x -x_1) + y_1$

This gives

$y = \frac 35(x -0) + 3$

Open bracket

$y = \frac 35x + 3$

Express y as a function of x

$f(x) = \frac 35x + 3$

Hence, the true statement about the graph of f(x) is $f(x) = \frac 35x + 3$

Suppose a friend of yours wants to buy a crystal candlestick. You remember seeing this item at both annie's attic and betty's br

Veronika [31]

The advice that will be given in the purchase of crystal candlestick is to go to

Betty's Breakables if the price is above $25.00.

In this scenario, we were told that Betty's Breakables offers 40% discount,

while Annie Attic offers $10 discount.

<h3>Calculation</h3>

Let's assume the price is $25.00, the discount at Betty's Breakables will be

= 40/100 × $25.00

= $10.

At Annie Attic, he was offered a $10 discount which is the same. However

there will be more gain on the discount if the price is above $25.

Let's assume the price is $30 , the discount will be $12 at Betty's Breakables

which is more than that at Annie Attic in which the discount remains at $10.

It is therefore cheaper to go to Betty's Breakable if the price of the

candlestick is above $25.
