For what value of the constant c is the function fcontinuous on (−[infinity], [infinity])?

Arlecino [84]

Answer:

For $c=\frac{1}{7}$ the function f(x) is continuous on $(-\infty,\infty)$ .

Step-by-step explanation:

We have the following function

$f(x) = \left\{ \begin{array}{ll} cx^2+5x & \quad x$

For the function f(x) to be continuous on $(-\infty,\infty)$ it is sufficient to have continuity at x = 6, we need to ensure that as x approaches 6, the left and right limits match, this means that

$\lim_{x \to 6^{-} } f(x)=\lim_{x \to 6^{+} } f(x)=f(x)$ ,

which holds if and only if

$c\left(6\right)^2+5\left(6\right)=\left(6\right)^2-c\left(6\right)\\36c+30=36-6c\\42c=6$

namely if $c=\frac{1}{7}$ .

Let Us Cell U charges $0.15/minute for long distance calls. Cell for Less charges $10.50/hour plus an additional $0.10/minute fo

docker41 [41]

Let Us Call <span>better</span>

translate 5 hours and 15 min into all min to find the total for us cell u. 5*60=300, so 315 minutes. So then multiply .15 by 315 and you get 47.25$.

<span>Now do Call for us. so first multiply 5 by 10.50. you get 52.50$.</span>
