Is xy equals 4 a function?
yes. it is a function
Is y equals x-4 a function?
Yes.
Is y equals negative 4 a function?
yes
Is x equals 4 a function?
No, x = 4 is not a function. I would describe x = 4 as the solution to an equation.
Is y equals 4 a function?
Yes, the function y=4 will be a straight horizontal line, passing through the point y=4.
Is xy equals 4 a function?
yes. it is a function
What is the slope of line with the equation 2x 3y plus 6 equals 0?
Put the equation in this form: y=mx+b. Then m will be the slope. 2x3y+6=0 2x3y=-6 3y=-6/2x y=-2/2x y=-1/x This equation does not describe a straight line, but rather, it describes a curve.
Is y equals x-4 a function?
Yes.
Is y equals negative 4 a function?
yes
Is x equals 4 a function?
No, x = 4 is not a function. I would describe x = 4 as the solution to an equation.
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 4 a function?
Yes, the function y=4 will be a straight horizontal line, passing through the point y=4.
Is x plus y equals 4 a function?
Yes.
Is y equals 2x plus 4 a function?
Yes.
Is y equals 3x-1 a function?
4
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
