Anybody know the answer???<br> f (-5) = ??
matrenka [14]

Answer:

7

Step-by-step explanation:

The function is f(x) so if x is replaced with a number, that's the value that x is in the equation. In this case, it'll be -5, so go to -5 on your graph. The y value is 7.

Show all work to identify the discontinuity and zero of the function f of x equals 4 x over quantity x squared minus 16
Leto [7]

Answer:

Discontinuity of function occurs when x = 4 or x = -4

zero of function is when x=0

Step-by-step explanation:

We are given:

f(x) = \frac{4x}{x^2 - 16}

Discontinuity of the function occur when the denominator is equal to zero.

So, we need to find the values of x that makes the denominator zero.

The denominator is x^2 - 16

x^2 - 16 =0

x^2 = 16

x = ± 4

So, if the value of x = 4 or value of x=-4 then the function will be discontinuous.

Zero of the function i.e f(x)=0

So, Putting the function equal to zero and finding the value of x

\frac{4(x)}{(x)^2 - 16}=0\\4x =0((x)^2 - 16)\\4x=0\\x=0

So, zero of function is when x=0

IfA=(-2,-4) and B=(-8,4), what is the length of AB?
lisabon 2012 [21]

Answer:

<h2>10 units </h2>

solution,

A(-2,-4)--->(X1,y1)

B(-8,4)----->(x2,y2)

now,

ab =  \sqrt{(x2 - x1) ^{2}  +  {(y2 - y1)}^{2} }  \\  \:  \:  \:  \:  =  \sqrt{ (- 8 - ( - 2)) ^{2} + (4 - ( - 4))  ^{2} }  \\  \:  \:  \:  =  \sqrt{( - 8 + 2) ^{2} +  {(4 + 4)}^{2}  }  \\  \:  \:  \:  =  \sqrt{( - 6) ^{2} +  {(8)}^{2}  }  \\  \:  \:  =   \sqrt{36 + 64}  \\  \:  \:  \:  =  \sqrt{100}  \\  \:  \:  \:  =  \sqrt{ {(10)}^{2} }  \\  \:  \:  \:  \:  = 10 \: units

Hope this helps..

Good luck on your assignment
