Answer:
A) 
Step-by-step explanation:
An equation is a function of 
when is the independent variable, that is:
(1)
Where 
is the dependent variable.
According to this, does not represent a function of , since the independent variable is a function of , that is, 
. Therefore, the correct answer is A.
Answer:
sqrt(2) =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hyp
sin 45 = x/2
2 sin 45 =x
2 ( sqrt(2)/2) =x
sqrt(2) =x
Ummmm................... I think you need to stick to the guidelines

Answer:
f(x)=3x^2+2x-10 if x=2
f(x)=3(2)^2+2(2)-10
f(x)=3(4)+2(2)-10
f(x)=12+4-10
f(x)=16-10
f(x)=6
g(x)=3x-3 if g(x)=2
g(x)=3(2)-3
g(x)=6-3 =3
Step-by-step explanation:
<u>f</u><u>(</u><u>x</u><u>)</u>
- replace x by 2
- do exponent
- distribute the brackets
- do addition and subtraction
g(x)
- replace x by 2
- distribute the bracket
- do subtraction
Prime
Prime numbers is a natural number greater than one
Prime has only one number that equals that number
For example: 37x1= 37
1x1=1
2x1=2
