Is the function given by f(x)equalsleft brace Start 2 By 2 Matrix 1st Row 1st Column one fourth x plus 1 comma 2nd Column for x

MArishka [77]

Answer:

C. The given function is continuous at x=4 because the limit is 2.

Step-by-step explanation:

Given the function:

$f(x)=\left\{\begin{array}{ccc}\frac{1}{4}x+1 &x\leq 4\\4x-11&x>4\end{array}\right$

We are to determine if the function is continuous at x=4.

For a function to be continuous at some value c in its domain:

f(c) must be defined.

$Lim_{x \to c}$ f(x)$ must exist.

$f(c)=Lim_{x \to c}$ f(x)$

Now: at x=4

$f(4)=\dfrac{1}{4}*4+1=2$

$Lim_{x \to 4}f(x)=2$

Since the two values are the same, we say that f(x) is continuous at x=4.

The correct option is C.

If someone can please help me out with my math, I would greatly appreciate it.

Answer:

The number of tickets they need to sell is $n=\frac{p}{(d-c)}$

Step-by-step explanation:

The formula is p = n(d - c), where

P is the total profit made from the event
n is the number tickets sold
d is the price charged for each dinner
c is the cost of food per plate

To find the number of tickets they need to sell separate n in one side and the other variables p, d and c in the other side

p = n(d - c)

n is multiplied by the difference of d and c, so lets divide both sides by the difference of d and c

$\frac{p}{(d-c)}=\frac{n(d-c)}{(d-c)}$

Cancel (D_C) up with (d - c) down in the right hand side

$\frac{p}{(d-c)}=n$

Switch the two side

$n=\frac{p}{(d-c)}$

The number of tickets they need to sell is $n=\frac{p}{(d-c)}$
