y - 3x = 7
can be written as
y = 3x + 7
For every value of x there is a unique value of y. For example when x = 0 y = 3(0) + 7 = 7
Yes it is a function.
In particular it is a one-to-one function.
The answer would be one because .9998 would round the 9 to a 10 which would round the second 9 and then the third nine to make 1
It is
If you have a slope (which is before the x) then it’s a linear equation

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume the graphed function comes from:

So this is the equation of a parabola that opens upward and whose vertex lies on the point:

The graph of this function is shown below. Which is true regarding the graphed function f(x)?
- It is true that the domain is the set of all real numbers because this is a polynomial function.
- It is true that the range is the set of all real numbers such that y ≥ 5
- It is true that this parabola opens upward
- It is true that it doesn't cut the x-axis
