What is x plus 4y equals 4 in function form?
y(x) = (4 - x)/4.
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?
All of them
Is y equals x-4 a function?
Yes.
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
Which function has the following a vertical asymptote at x equals -4 horizontal asymptote at y equals 0 and a removable discontinuity at x equals 1?
2x-2/x^2+3x-4
What is x plus 4y equals 4 in function form?
y(x) = (4 - x)/4.
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?
All of them
Is y equals x-4 a function?
Yes.
Is this equation a function -x plus y equals -4?
Yes it is a function. In standard form it is y=x-4.
Is x plus y equals 4 a function?
Yes.
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
Which function has the following a vertical asymptote at x equals -4 horizontal asymptote at y equals 0 and a removable discontinuity at x equals 1?
2x-2/x^2+3x-4
How do you rewrite as a function of x using function notation for 2x plus 3y equals 4?
If 2x + 3y = 4, y= (4 - 2x)/3. In function notation, f(x) = (4 - 2x)/3.
Is y equals x - 4 a linear function?
Yes, since y changes proportionally with x.
What is another name for the root of a function?
The "root" of a function is also called the "zero" of a function. This is where the function equals zero. The function y=4-x2 has roots at x=2 and x=-2 The function y=4-x2 has zeroes at x=2 and x=-2 Those are equivalent statements.
What is the rule for the function x equals 0 1 2 3 4 y equals 8 6 4 2 0?
y = 8 - 2*x
What is the function rule of y equals 2x if x equals 1 2 3 and 4?
y = 2, 4, 6, 8
