Please help. I don't understand what to input into the c...

Factorize the denominator:

$x^2-31x+240 = (x-16)(x-15)$

Then we find that ...

• When <em>c</em> = 15,

$\displaystyle \lim_{x\to15}f(x) = \lim_{x\to15}\frac{x-15}{(x-16)(x-15)} = \lim_{x\to15}\frac1{x-16} = \frac1{15-16} = \frac1{-1} = \boxed{-1}$

because the factors of <em>x</em> - 15 in the numerator and denominator cancel with each other. More precisely, we're talking about what happens to <em>f(x)</em> as <em>x</em> gets closer to 15, namely when <em>x</em> ≠ 15. Then we use the fact that <em>y</em>/<em>y</em> = 1 if <em>y</em> ≠ 0.

• When <em>c</em> = 16,

$\displaystyle \lim_{x\to16}f(x) = \lim_{x\to16}\frac{x-15}{(x-16)(x-15)} = \lim_{x\to16}\frac1{x-16} = \dfrac10$

which is undefined; so this limit does not exist.

• When <em>c</em> = 17,

$\displaystyle \lim_{x\to17}f(x) = \lim_{x\to17}\frac{x-15}{(x-16)(x-15)} = \lim_{x\to17}\frac1{x-16} = \frac1{17-16}=\frac11 =\boxed{1}$

because the function is continuous at <em>x</em> = 17.

It would be 2*(5^2)
(2 multiply to (5 rise to the power of 2))
Hope that help.

Danielle wants to buy a video game. At the local Big Box store, it costs $49.95. Danielle has a coupon for 10% off at the store,

KATRIN_1 [288]

Here are the answers to the questions above. Given the problem, let us solve first for the cost of each store. At a local store, it costs $49.95. Since she has a 10% off discount, the amount that she will be paying is $44.955. Since, there is a 6.5% tax, the total amount she will be paying is $48.20. Now, for the online store, it costs $44.95 plus a shipping charge of $4.00 so the total would be $48.95. Given these results, it would be cheaper if she buys in the local store. Hope this helps.
