A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
The linear equation x=5 or any other number is a vertical line. There are more than one possible answer for y. Therefore it is not a function.
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
The equation x=c where c is a constant is the equation of a vertical line. It can't be a function but it is linear so the answer is no. For example, the vertical line produced by the linear equation x = 3 does not represent a function. We cannot write this equation so that y is a function of x because the only x-value is 3 and this "maps" to every real-number y.
yes, a vertical line is linear, but it's not a function.
Linear function
Yes, a vertical line is linear, but it is not a function, because every point on the line has the same x value.
It is a function. If the graph contains at least two points on the same vertical line, then it is not a function. This is called the vertical line test.
A linear equation
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
X = 3 A vertical line not having a Y intercept.
The linear equation x=5 or any other number is a vertical line. There are more than one possible answer for y. Therefore it is not a function.
Yes, 2y = 8 is a linear function. 2y = 8 is the same as y=8/2, or y=4, which is a vertical line.
