Sketch f(x) = 5x2 - 20 labelling any intercepts.​
Norma-Jean [14]

Answer:

  • The graph of the function is attached below.
  • The x-intercepts will be: (2, 0), (-2, 0)
  • The y-intercept will be: (-20, 0)

Explanation:

Given the function

f\left(x\right)\:=\:5x^2-\:20

As we know that the x-intercept(s) can be obtained by setting the value y=0

so

y=\:5x^2-\:20

switching sides

5x^2-20=0

Add 20 to both sides

5x^2-20+20=0+20

5x^2=20

Dividing both sides by 5

\frac{5x^2}{5}=\frac{20}{5}

x^2=4

\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}

x=\sqrt{4},\:x=-\sqrt{4}

x=2,\:x=-2

so the x-intercepts will be: (2, 0), (-2, 0)

we also know that the y-intercept(s) can obtained by setting the value x=0

so

y=\:5(0)^2-\:20

y=0-20

y=-20

so the y-intercept will be: (-20, 0)

From the attached figure, all the intercepts are labeled.

After the following code runs, what will be the value of result? var x = 30; function get () { return x; } function set (value)
PilotLPTM [1.2K]

Answer:

Null

Explanation:

It entirely depends on the language you are using to implement this.

But generally by the rule of scope, "result" will return null since get() was not defined to accept any argument, and it neither know the global "x" not defined it's own x in the function.

Which of the following is an example of joint problem solving?
tatuchka [14]

Explanation:

There is a high degree of informality to these relationships, which are focused on information sharing, joint-problem solving and joint operations.

A hallmark of most of these processes is their informality, whether through information sharing, joint problem solving or joint operations.

Global joint problem-solving team. In addition to requesting a division of labour, the Global Task Team recommendations called upon the World Health Organization (WHO), UNICEF, the United Nations Population Fund (UNFPA), the United Nations Development Programme (UNDP), the World Bank, the UNAIDS Secretariat and the Global Fund to take the lead in and establish the joint United Nations system-Global Fund problem-solving team by July # in order to support efforts that address implementation bottlenecks at the country level
