It means that the value of the function at any point "x" is the same as the value of the function at the negative of "x". The graph of the function is thus symmetrical around the y-axis. Examples of such functions are the absolute value, the cosine function, and the function defined by y = x2.
What else can I help you with?
What does it mean if a zero of a function is 4?
It means the value of the function equals zero when the argument is 4. For example: f(x)=x-4 f(4)=4-4=0
Is the function f of x equals one divided by x an example of a rational function?
True
Is f of x equals x plus x plus 5 a linear function?
Only if it's a function.
Is x equals 5 a function?
yes, it is.
Is the y3 equals x is linear function?
no
Can a function be defined as x equals a but not have a limit at x equals a?
exactly...
What is the average rate of change from x equals 2 to x equals 3 for the function f of x equals 3 ln x?
It is 1.2164
Is x equals y a function?
y = x This is a line and a function. Function values are y values.
What does it mean if a zero of a function is 4?
It means the value of the function equals zero when the argument is 4. For example: f(x)=x-4 f(4)=4-4=0
Is the function f of x equals one divided by x an example of a rational function?
True
How do you know that y is a function of x?
If you plug in y for the x function, and it equals the answer you got, it is right.
Isy equals x a function?
Yes.
Is x equals 5 a function?
yes, it is.
Is the y3 equals x is linear function?
no
Is f of x equals x plus x plus 5 a linear function?
Only if it's a function.
What is the solution for function of function of x equals function of x?
f(f(x)) = f(x). Only if f is 1-1 then we have a solution f(x)=x.
Which one is a function f x equals 4x F X equals X subtract 4 f x equals x plus 4 or F X equals negative 4X?
