The function y equals sin θ is not a function beacause sin 30 equals sin 150?
Y=sin X is a function because for each value of X, there is exactly one Y value.
What is the inverse of y equals x?
The inverse of the function y = x is denoted as y = x. The inverse function essentially swaps the roles of x and y, so the inverse of y = x is x = y. In other words, the inverse function of y = x is the function x = y.
Is y equals x2 plus 1 a function?
Yes. Think of y as being a function of x. y = f(x) = x2 + 1
What is y in y equals x sin wt?
Without additional information, one can only say that y is a function of x, w and t.
What will happen if y equals x plus 2 was changed to y equals x-1 what will the graph of the new function compare with the first one?
It would be less steep
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.
Is y equals -x plus 2 a linear function?
Yes, y=-2+x is a linear function.
Does y vary directly as x in this function y equals x plus 2?
No.
Is x-y equals 5 a function and how?
X - Y = 5 - Y = - X + 5 Y = X - 5 ==========Now it is a function because it passes the vertical line test.
The function y equals sin θ is not a function beacause sin 30 equals sin 150?
Y=sin X is a function because for each value of X, there is exactly one Y value.
What is the inverse of y equals x?
The inverse of the function y = x is denoted as y = x. The inverse function essentially swaps the roles of x and y, so the inverse of y = x is x = y. In other words, the inverse function of y = x is the function x = y.
If Sin equals x and Cos equals y then x squared equals what function of y?
If x = sin θ and y = cos θ then: sin² θ + cos² θ = 1 → x² + y² = 1 → x² = 1 - y²
What type of function is represented by the equation y equals -2lxl?
y - |x| is an expression, not a function.
Is y equals x2 a function?
Y=X^2 is a function for it forms a parabola on a graph.
What is the range of the function y equals x?
The function y=x is a straight line. The range is all real numbers.
Is this equation a function -x plus y equals -4?
Yes it is a function. In standard form it is y=x-4.
Is y equals -x in function form?
Yes.
