How do you write y equals 2xsquared plus 4x-7 in function notation?
f(x) = 2x2 + 4x - 7
How do you solve X9 - Y6 equals X3 - Y2 Between each X and Y power is an exponent?
2x2-y2
Is y equals 2x2 a function?
no
What notation represents a function as f x instead of y?
'Y' is a function 'f' of 'x': Y = f(x) . 'Z' is a function 'g' of 'y': Z = g [ f(x) ] .
Is y equals x2 a function?
Y=X^2 is a function for it forms a parabola on a graph.
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.
How do you write y equals 2xsquared plus 4x-7 in function notation?
f(x) = 2x2 + 4x - 7
How do you solve X9 - Y6 equals X3 - Y2 Between each X and Y power is an exponent?
2x2-y2
Relation is a function y equals -8?
determine whether each relation is a function y equals -8
Is x equals y a function?
y = x This is a line and a function. Function values are y values.
Is y equals 2x2 a function?
no
How do you write 4x2 plus y equals 16 using function notation?
First you need to solve for y. So write 4x2+y=16 so y=16-4x2 Now write f(x)=16-4x2
What notation represents a function as f x instead of y?
'Y' is a function 'f' of 'x': Y = f(x) . 'Z' is a function 'g' of 'y': Z = g [ f(x) ] .
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.
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.
Is y equals 8 a function?
Yes.
