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
Answer:
Step-by-step explanation:
The hypothesis needs to explain the certain conditions that need to exist in order for a specific conclusion to take place. Meaning that if these conditions are not present in the scenario, then the conclusion would be different or simply not exist. Based on this info we can say that the hypothesis is "2 lines are perpendicular" while the conclusion is "The lines form 4 right angles"
Answer:
- y-intercept: (0, 3)
- axis of symmetry: x = -1
Step-by-step explanation:
The y-intercept is the constant, 3. It is the value of f(0).
__
The axis of symmetry of the quadratic function ...
f(x) = ax^2 +bx +c
is ...
x = -b/(2a)
Here, using that formula gives ...
x = -(2a)/(2(a)) = -1
The axis of symmetry is x = -1.
