Which of the following is not a disadvantage of using cash instead of credit?

sergeinik [125]

The <em>correct answer</em> is:

D) Using cash can make it easier to over-spend since you know exactly how much you have.

Explanation:

Knowing exactly how much you have on hand will actually help you avoid over-spending.

When using cash, you are aware of exactly how much money you have. With a credit card, this may not be the case; this makes it easier with a credit card to spend more money than you should for your budget. With cash it's easier to avoid this problem.

If we graph the given points then they appear to be in the shape of cubic function so we can use standard formula of cubic function which is

$y=ax^3+bx^2+cx+d$

Plug the given points to get four equations

like first point (3,6) so plug x=3 and y=6 into above equation, we get:

$6=a*3^3+b*3^2+c*3+d$

or

6=27a+9b+3c+d

Same way by plugging other points form table, we get total four equations as follows:

6=27a+9b+3c+d, 11=125a+25b+5c+d, 11=64a+16b+4c+d, 21=343a+49b+7c+d

Now we just need to solve these equations for a, b, c and d.

Solving them to get values of a, b, c and d, we get:

$a=\frac{25}{24}, b=-15, c=\frac{1715}{24}, d=-\frac{203}{2}$

Now plug them into

$y=ax^3+bx^2+cx+d$

So the required equation will be:

$y=\frac{25}{24}x^3-15x^2+\frac{1715}{24}x-\frac{203}{2}$

Hence required equation in function notation can be written as

$f(x)=\frac{25}{24}x^3-15x^2+\frac{1715}{24}x-\frac{203}{2}$

Now to prove that above function is correct, we just graph the given points from table and the obtained function.

After graphing the given points from table and the obtained function, We see that points lie on the graph of $y=\frac{25}{24}x^3-15x^2+\frac{1715}{24}x-\frac{203}{2}$

Which proves that our equation is correct.
