Answer:
B. False
Step-by-step explanation:
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
D= 687-365
d is your answer to the question or the outcome
Answer:
14.14
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(10 - 20)² + (25 - 15)²
√(-10)² + (10)²
√(100) + (100)
√200
= 14.14
