is the answer 1/sqrt(3) x + 5 ?

That isn't an equation.

 

[boredsatan]

That isn't an equation.

y = 1/sqrt(3) x + 5 ?

 

[InteGrand]

y = 1/sqrt(3) x + 5 ?

Correct!

 

[boredsatan]

No

y = 1/sqrt(3) x + 5
3y = √(3) x + 15
are these the same?

 

[InteGrand]

y = 1/sqrt(3) x + 5
3y = √(3) x + 15
are these the same?

Yes

 

[boredsatan]

Yes

You should know the shapes of the graphs of some standard functions. For other ones, you can sketch them with the help of calculus to find turning points and so on. There is a ''curve-sketching recipe'' in some textbooks (like one of the Pender ones) that you can have a look at, or find online.

[InteGrand]

How do you find the image of 0 for 3x^2 + 2

Sub. x = 0 into the expression.

 

[boredsatan]

Sub. x = 0 into the expression.

so if it was the image of 4, sub 4 in the equation, etc

 

[InteGrand]

Yeah
