In the expression f(x)=23, x is not a variable. f(x) means “a function of x” or “f of x” and is in practice another way of substituting for the variable y, that is, we are saying:
y=23.
That means x is unspecified and could be anything. So on the xy plane, this is a straight horizontal line, 23 units above the x axis. That would be the best way to interpret this, although it is a little ambiguous.
Usually functions of x are expressed in terms of x, such as:
f(x) = x^2
It is as 5x's as much.
<em>$0.30 X 5 = $1.50</em>
Hope I helped
Yes this is equal because 3v+v is 4v and if you divide 12v by 3 you also get 4v
Answer:
it's easy hope I could help
Step-by-step explanation:
the -3 goes on the y line
4/3 goes on the positive side so on the y and x
